Twins and twins: what's the difference? How are the twins and twins arise, how is conception? Are the twins or twins are similar to each other?

In this material, we will consider the difference between twins and twins.

Content

Twins, twins - these concepts are considered completely different. This is the name of different children. At the same time, both the first and second are born together, but they have distinctive external features. The phenomenon of twins our medicine is not able to explain. There are several options for how the development of pregnancy itself occurs, which leads to the appearance of twins or twins. We will try to figure out in more detail.

Who are twins and twins, how they look: photo

All the same one twins are identical people and are very similar in appearance to each other. It is especially difficult to distinguish them in childhood. There are several types of twin children.

Identical

Very often their appearance is a reflection of each other, as if in a mirror. For example, one of the twins has a birthmark on the right cheek, but the second twin will be on the left cheek.

Also, such twins have an identical shade of eyes, hair, and skin. Their teeth are located the same way, plus they have the same blood and prints of each finger.
You can no doubt (if necessary) transplant a certain organ or fabric between such twins. However, everything will pass successfully. It is amazing that people are also sick with similar diseases, at the same time.

It is a pity, but it is impossible to plan the emergence of such children. This cannot even affect the mother of the mother.

Semi -identical

Half -identical twins are usually monozygous twins. However, they have some differences, thanks to which they are not always similar to one -eating twins - children can be born different sexes.

Outwardly, such people are very similar to each other, but girls and boys can be born at the same time
Such people have exactly the same genes with their mother, and only 50% of their father’s genes. The twins coincide with their own genetic similarity only 2 \\ 3

For example, if the mother of the African, and dad is a Chinese, then one baby can be born black -skinned, and the second - fair -skinned.

Dizigot (twins)

These twins are either the same gender, or different. People can coincide with a maximum of 60%of their own genetic similarity. In addition, it is possible to transplant a certain organ or fabric from each other, but not in all cases.

Twins are born unexpectedly, such a process is simply impossible to plan
Often twins are born in those parents who use the eco method

Twins look like the most ordinary children. They can be similar strongly or not very. Also often twins have different blood groups.

Are the twins or twins are similar to each other?

As we know, a multiple pregnancy is a process during which a fertilized egg is not quite normally shared or two or more eggs are fertilized. The birth of one -eating twins is an accidental event. The birth of bilingual and multi -tower twins is a genetically determined sign, since there is a certain pattern. That is, in women who have twins in the family, the probability of multiple pregnancy increases significantly.

Twins:

Two or more kids who develop in one uterus are considered twins and are born almost at the same time. As a rule, twins are divided into one -euthy and multi -tower (bilingual).
Odinoi is born thanks to one fertilized egg, when it is divided at different stages for a couple and more parts. Such twins basically appear similar to each other, almost always such children are born the same sex.
In addition, they have similar characters, plus they do not differ completely with habits, hobbies and interests.

Twins:

If fertilization occurred thanks to two or more eggs, then twins are born. Children are born similar to each other, can have similar character traits, there are also different sexes.
Twins are born only 2% of all newborns. They have different external features, characters, taste preferences.
Often, after a multiple pregnancy, children are born who have a low weight, since they are in large cases premature. Women who bear twins most often complain of preeclampsia or eclampsia.

What is the difference between twins and twins: similarity and difference

Gemini differs from twins with their genotype. The twins have the same genes, and therefore they are often called monozygous twins. Twins are any twins, both monozygous and dizygos.

There can be twins: a girl and a boy or same -sex children. Gemini are constantly born of the floor. They are born similar, like two drops of water, even their birthmarks are in the same places.
The distinctive features between the twins and the children begin to be laid during ovulation, and then in the process of fertilization. During ovulation, a pair of eggs ripens and fertilizes simultaneously. In this case, ordinary twins are born. “Royal twins” may be born: one child is a girl, the other is a boy.
Of course, if a fertilized egg begins to share before implantation, it will give the life of two twin babies. But the implantation of the fruits will be carried out separately, that is, such a process will occur as during the fertilization of two eggs.
The possible appearance of twins and twins can be recognized when passing a pregnant ultrasound. During pregnancy, a woman can always find out by the structure of the shells of the floor of future babies, how many of them will be born, whether they will be twins or twins. The difference, of course, will be noticeable if the kids have a different floor or if the twins are dichorial diamniotic.
However, in this case, surprises are possible. After the kids are born, it is found that they have similar external features, that is, they are twins. Although the woman during her pregnancy was sure that she was expecting different kids.

The difference and similarity of twins and twins

You can distinguish twins from twins immediately as they are born:

Gemini, born from different eggs, are heterosexual. But those born from one egg - one floor.
There is such a risk that twins are born even from different dads. But this is rare. If you take the twins of the same one, then they always have one dad for two.
The same tyce twins are similar to each other. And twins have some differences in appearance.
In single -tie twins, blood is the same, in twins can differ significantly.
If you take development, then twin children are born in one placenta, and twins in different ones.

Now consider what twins can be like twins.

Both the twins are one -eating, and twins are very similar in childhood. The similarity of one -eating twins is sometimes so large that mothers and dads are not always able to distinguish them. But the similarity of twins is much lower, but present. This is because the kids are born from one mom and dad, have an identical genetic set, plus they are born almost together.
Often such babies become donors for each other. The same tyce twins are considered absolutely identical, and therefore are ideal donors. Sometimes twins become donors, since they are considered relatives.

How are the twins and twins arise, how is conception?

There are two effective methods that lead to the birth of twins or twins:

1 method - hormonal stimulation is carried out. It allows you to produce several live eggs at once.
2 method - Eco is carried out. During this procedure, the eggs are fertilized in test tubes and after that they are transferred to the uterus of the future mother.

The following factors can be affected by multiple pregnancy:

Correct counting. A woman who wants to have twins starts a special calendar and watches him at least six months.
Such conception is affected by the duration of menstruation. If the menstrual cycle is short (about 21 days), then the chance to give birth to twins increases significantly.
An anomaly in the development of the uterus itself can also be affected. That is, bifurcation, presence in the uterus of the partition.

But, but what is stimulation? How is the fertilization of the egg after this procedure?

In the ovaries, when they are in a calm state, hormonal drugs are administered for about 3 months. The process control is carried out artificially. After ovulation occurs in one ovary, the second ovary begins to function. Then hormonal drugs are canceled, as a result of which 2 appendages are turned on, which form a couple of eggs. A similar process in medicine is called the effect of the rebound.
The effect of the rebound and its appearance cannot be influenced. However, due to the stimulation of ovulation with the help of medicines, the maturation of several follicles occurs simultaneously. In this case, fertilization of a pair of ripened eggs or only one occurs.
IVF is carried out after the artificial stimulation of each ovary is carried out and female germ cells are obtained. At least 4 eggs are fertilized, but how much can take root is unknown.
Each embryo will be able to take root at the same time or only 2. No matter how much they take root, they always leave 2. Therefore, IVF is the main method that guarantees the birth of twins.
In some situations, even if fertilization was successfully carried out, the cell does not survive the “artificial landing”, and therefore does not take root.

Now we will find out how the fertilization itself is happening:

If during conception a fertilizes several eggs with spermatozoa (two or more) is simultaneously fertilized, then twins, sometimes triplets and more children are born.
If the egg is fertilized 1 sperm, then ordinary twins are born.

The chance of the birth of twins, as scientific research and long -term medical practice show, are much higher than twins. However, doctors at the same time cannot reveal the secret of that phenomenon when people who are similar to each other are born by almost 100%.

Boy and girl: Are these twins or twins?

What is royal twins? This is a certain secret of nature or a present donated by fate to the chosen people. Or maybe this is some kind of test? Of course, a couple of peanuts that are similar to appearance, but have different floors (girl and boy) are great happiness. At the same time, this is a huge responsibility, to which gene deviations can still be added.

As statistics shows, the twin babies are different sexes is a very rare phenomenon. Therefore, even doctors cannot assume that future parents will be born "royal twins." Since heterogeneous children are often a process during which 2 eggs are fertilized, as a result of which twins are born. Be that as it may, there were such cases when the born twins (boy and girl) had exactly the same external features. So who is really a boy and a girl: twins or one -eating twins?

You should not exclude a phenomenon when twins of different sexes are born exactly the same. This is possible, but very rarely. We know that the fertilization of the twins occurs due to one zygote, and therefore they have similar chromosomes. However, there are some factors and inexplicable processes during which boys and girls are born, not twins. Such fertilization is possible in the following cases:

When the boy was lost in the boy during conception.
If one of the kids has an excess chromosome X. This phenomenon has the name Clinfelter syndrome.
When the egg shared to fertilization. In this case, the egg is fertilized with various sperm, and therefore babies can have different floors.
When the fertilization of the egg is carried out due to two male cells. In this case, the kids are born completely healthy, without deviations at the genetic level.

Of course, a boy and a girl are twins. But there are times when they are born twins, having the same appearance.

Why is it believed that twins and twins live longer?

American scientists have come to one conclusion - they argue that twins and twins can live longer than other people, and rarely die at a young age. Experts say that such people help each other, support throughout life.

Scientists were able to compare the data obtained in thirty years (from 1870 to 1900). They found out that the twins do not often die from all kinds of unforeseen diseases. But, when they are 60 years old, the health of the twins deteriorates, and the reason for this is the active influence of genetic factors.

So, in the twins, life factors increase by about 10%. Girls and women twins are stronger than men. Also, men and women have a huge connection between each other. Sometimes even they dissuade their brothers and sisters so that they abandon bad habits.

Experts also found that the same -eating twins may have a more favorable life than in the Multiyayytsevs. Although they also have a greater advantage in terms of longevity, when compared with ordinary people.
