Parents double eyelids, is it more likely that the child will become double after tomorrow 40

It is very large, if either parent has double eyelids, it is very likely that the child has double eyelids, but there are also a small number of single eyelids.

Possibly. If eyelids are thin or there are occasional rucks.

But if the single eye is too powerful or the eye itself is a bubble eye, the possibility is very small.

If the parents have double eyelids, the child will generally also have double eyelids, so the possibility of becoming double is very high, and there are many genetic factors.

It is possible, even if it is not naturally formed, then the current medical plastic surgery is so developed, and the whole double eyelid is not a difficult thing, my Niuniu was born with double eyelids, but it is not when the full moon is full, and now it is 10 months old or single eyelid.

It is unlikely that the acquired pair will become double, and now the single eyelid is popular, there is no need to pay attention to one, as long as the child is healthy.

There is a possibility that it will become a double. But there are also single eyelid babies with double eyelids. Actually, there is nothing wrong with a single eyelid. The boy's single eyelid is handsome, the girl's single eyelid is delicate, and she looks good with a little makeup when she grows up.

No, double eyelids are natural, and they will not become double eyelids because the parents have double eyelids.

The possibility is very large, the general parents have double eyelids, and the baby generally has double eyelids!

I think it's a possibility, but it depends on whether your parents' genes are recessive, but it's still a big possibility.

It's more likely, but it doesn't matter if it's inconvenient.

It's possible.,I'm born with a single point skin.,My parents are double.,I've become a double now.。

Addendum: My own brother was also single when he was a child, and he had an illness when he was in his teens, and then he became a pair.

Double eyelids are possible, but single eyelids are also possible.

Well, it is very likely, the singer Jacky Cheung only had an inner double at the age of 40.

Yes, double eyelid genetics is obvious.

Huge, the kid has absolutely double eyelids.

The two of us also have double eyelids, but the baby has been a single eyelid for 6 months now, but no matter whether the baby has double eyelids or single eyelids, only he is healthy and healthy.

Possibly. As long as the seeds are correct.

If both parents have double eyelids, the baby must have double eyelids.

Both parents are double, that's quite big!

This is not good, my husband and I are double eyelids, my baby is now seven months old, anyway, it hasn't changed at all, maybe this is the principle of positive and negative.

Children inherit 80 percent of their parents' genes.

Is it more likely that the child will have double eyelids when the parents have double eyelids?

Summary. Hello!

Mom and Dad both have double eyelids, and Mom comes to have double eyelids, so there is a high possibility that their children will have double eyelids.

Mom and dad both have double eyelids, but mom is a posterior, is it possible for the child to change?

Hello! Mom and Dad both have double eyelids, and Mom comes to have double eyelids, so there is a high possibility that their children will have double eyelids.

In fact, my mother originally had double eyelids, but it was not very obvious, so it was regarded as a double eyelid. Can you "become" the double eyelids, you can look in the mirror to see if the double eyelids of the self-imperial Lu Ji are not, and gently pull down the eyelids with your hand to see if they overlap the bucket calendar.

Dad's double eyelids are born Mom is posterior, and then my brother is also posterior, so will my sister.

My sister will also become double eyelids

The little beauty is very beautiful, wow!

There is this possibility, the baby will gradually shape in the process of growth and development, the inner double may become the outer double, if it is a single eyelid, it should be the role of genetics, may not change, it may have been the inner double, some may change over.

It is very likely that if one of the parents has double eyelids, and it is also a double eyelid. Then the child is likely to become an outer pair in the future.

It is also possible that the general baby's eye state will still undergo some changes in the later stage, but the probability is not too high.

This depends on the genes of the parents, if both parents have double eyelids, the child will have a high probability of turning into a double eyelid, if both parents are that pair then the chance is very small.

Although the aesthetics of modern people have been changing, there are indeed many single-eyelid beauties that are liked by everyone. However, from the perspective of the general environment, people's aesthetics still tend to double eyelids. So moms and dads more or less want their children to have a pair of attractive double eyelids!

However, some parents have double eyelids, but the birth of a child is a single eyelid. If it is all single eyelids, is it possible for the child to have double eyelids?

However, whether a child exhibits certain genetic traits depends largely on whether the parents are dominantly or recessively inherited for these traits. What about the so-called dominant inheritance and recessive inheritance? How are single and double eyelids inherited to babies?

Double eyelids are considered to be dominantly inherited and single eyelids are recessive. If both parents have a single eyelid, the child should generally have a single eyelid as well. If both parents have double eyelids, in general, the child should have double eyelids as well, but occasionally there are single eyelids.

In terms of genes, we can explain the genes on the chromosomes that determine whether a human has a single eyelid or a double eyelid, and we can assume that the letters a and a represent the genetic factors of double eyelid and single eyelid, respectively. Because double eyelids are dominantly inherited, when A and A meet together, as long as A exists, they are realized into double eyelids, and single eyelids will appear unless there are two A's in the gene.

In other words, although both parents have double eyelids, they both have a single eyelid gene, and when the single eyelid gene from both parents is paired, the child will become a single eyelid.

As for whether a child born to parents with single eyelids will have double eyelids, biologically speaking, intergenerational inheritance and recessive inheritance are possible. Some experts explained: both couples have single eyelids, which does not mean that neither of them carries the gene of double eyelids, but the probability of a child's double eyelids is smaller, and it is possible that the child has a single eyelid and a double eyelid.

In fact, whether the baby has single eyelids or double eyelids, it is the love of parents. Small eyes are as fascinating, right?

No way. Because single eyelid is a recessive gene, if both parents have single eyelids, then there is no dominant gene for double eyelids, so the child will not have double eyelids.

In humans, double eyelids are controlled by dominant genes, while single eyelids are controlled by recessive genes. Regardless of whether the parents have single or double eyelids, the probability of a child having single and double eyelids is 2:1.

It is very likely that the child has double eyelids, because if both parents have single eyelids, it is very likely that double eyelids are recessive genes in the parents' generation, and they will be shown here in the child.

No way. Because the parents have a single eyelid, the child must have a single eyelid, which involves the genetics of biology.

It may be a double eyelid or a single eyelid.

A baby's single and double eyelids are genetically determined by the parents. There are "dominant genes" and "recessive genes" in genes, and dominant genes are genes that determine their performance characteristics in a pair of genes, which is called phenotype; Recessive genes, on the other hand, determine their performance traits only when they are present in pairs. Among single and double eyelids, double eyelids are dominantly inherited, and single eyelids are recessive.

Suppose the letter A represents the double eyelid gene, and the letter A represents the single eyelid gene. A is the dominant gene and A is the recessive gene. As long as a is present, it is possible to inherit double eyelids; However, if there are 2 A's in the gene, there is a possibility of a single eyelid.

One of you has a single eyelid and the other has a double eyelid, the combination may be AA+AA, or AA+AA, and the child born may be AA, AA or AA, which means that the baby may have double eyelids or single eyelids.

Every baby's situation is different, some babies are born with double eyelids, and some don't see it until a few months later. Some of them become double eyelids when they are bigger. However, if the couple is double eyelids, the probability of baby double eyelids is 50%, if you want a beautiful double eyelids, it is recommended to choose the double eyelid cutting method, in general, the risk of double eyelid incision surgery is not high, but there may be some symptoms after surgery, as long as you take good care of it, you can return to nature.

There will always be such situations in daily life, some people have double eyelids, some people have single eyelids, some people have flat forehead angles, and some people have beauty tips. Both parents have double eyelids, and children may have double eyelids or single eyelids, but both parents have single eyelids but cannot give birth to children with double eyelids, so why do the same genetics of parents have different form characteristics? The answer is the difference in traits.

It is for this reason that parents with single eyelids are unable to give birth to children with double eyelids.

Traits are divided into dominant traits and recessive traits, as the name suggests, dominant traits are more common characteristics, and recessive traits are less common and less obvious trait characteristics. A single eyelid is a recessive trait. The genome of dominant traits and there are two kinds of xx and xy, and recessive traits can only be formed by yy.

So if both parents have double eyelids, then if the genetic factors of both people are xx, and only one of their genetic types is x, so the trait of the child after the combination is also xx, which is the dominant trait, double eyelids. If one person is xx and the other person is xy, then one of the genetic factors is x, and the other person can be divided into two, x and y, and the child is xx and xy after cross-combination, which is also a dominant trait and is a double eyelid.

In the last case, when both parents are XY and XY type trait factors, then two X and two Ys can be separated, and after cross-combination, four traits can be formed: xx, xy, xy, yy, and so on. There is a three-quarters probability that the child will have a dominant double eyelid and a one-quarter single eyelid. Therefore, both parents have double eyelids, and the child may also have single eyelids.

In the same way, if one parent has one eyelid and the other has double eyelids, then it is possible for the child to have both single and double eyelids. However, if both parents have a single eyelid, then the trait only has a composition, that is, yy, and its genetic separation can only isolate the factor y, so the trait after the combination of parents is still yy, the recessive trait single eyelid. Therefore, it is impossible to give birth to a child with double eyelids.

Human double eyelids are controlled by dominant genes (A), and single eyelids are controlled by recessive genes (A), so the genetic composition of a single eyelid child is AA, one of which A must be from the father of the boy, and a A must be from the boy's mother, and his parents are both double eyelids, which must contain dominant genes A Therefore, a single eyelid pats back to the child's parents are double eyelids, and the genetic composition of the parents must be AA Genetic** as shown in the figure: It can be seen from the genetics**: their first child is a single eyelid, The second child has a 75% chance of having double eyelids
