Both husband and wife have single eyelids, is it possible for the baby to have double eyelids?

Is it possible that both husband and wife have double eyelids, and the child born is a single eyelid? Yes: Absolutely!

Let's take a look at some of the things we need to know about heredity. 1. What is dominant inheritance and recessive inheritance?

Almost all parents in the world want to pass on their own advantages to their children, and try to avoid genetic shortcomings. But hope is hope, and in fact, all the characteristics of the parents, including all your strengths and weaknesses, are actually inherited to the child with the same odds. Whether a child embodies certain genetic traits depends mainly on whether the traits are dominantly or recessively inherited, so what is dominant inheritance?

It refers to the inheritance that can manifest characteristics under the influence of the genetic factors of one of the parties. Recessive inheritance, on the other hand, refers to inheritance that requires the genetic factors of father and mother to pair up in order to exhibit characteristics.

For example, a single eyelid is controlled by a recessive gene, and a double eyelid is controlled by a dominant gene. If both husband and wife's genes are dominant, then the child must have double eyelids. But if there is a person's gene or two people's genes, half of which are dominant and half are recessive, and the baby happens to inherit the recessive gene of the father, mother or both parents, it will be a single eyelid, which is not a minority, and the probability accounts for 25%.

Ordinary people think that their children will be the same as themselves in all aspects, but this is not the case. In biology, we have learned the laws of gene inheritance, and through Mendel's pea hybridization experiments, we know the law of gene segregation and the law of free combination of genes, and the occurrence of this phenomenon can be explained by the gene segregation theorem we have learned. Both husband and wife have single eyelids, and the baby may have both single and double eyelids, depending on the parents' genes.

Our neighbor is a good example of this. The child's mother has double eyelids, and the child's father also has double eyelids, but the first child they give birth to is a girl, and the girl has a single eyelid, and when their second child, a boy, is born, and the little boy has double eyelids, and sometimes even becomes triple eyelids, and this happens from time to time.

There is also a good example to illustrate this situation. This is the case of a relative of mine, who wanted a beautiful child with very good eyes and double eyelids, but God did not wish that, although the parents of the child had double eyelids, but the child ended up with single eyelids.

Of course, I'm sure there are a lot of families who will have this experience. In other families, one parent has a single eyelid and one has a double eyelid, but the baby is born with a single eyelid, or double eyelid. Therefore, what kind of eyelids the baby looks like in the end, all are random, and it does not necessarily mean that the parents are single eyelids, so the child will not have double eyelids, even if the probability is relatively small, there will be a possibility of appearing.

Both couples are single eyelids and have a double eyelid baby The probability is not high, single eyelid is a dominant gene, but it does not exclude the inheritance of other relatives who are related by blood, and the children born to my husband and wife with single eyelid are single eyelids.

There are certain odds! But it can be said that the odds are very small! I feel that the single eyelid is also very beautiful!

One of the husband and wife has a single eyelid.

One person has two eyelids.

Will the child have single eyelids or double eyelids?

Double eyelidsThe main manifestation of microbial strains in the process of genetic decision-making is that if the parents are single eyelids for each other, children generally have single eyelidsIf one parent has one eyelid and one double eyelid or both have double eyelids, the chances of future generations having double eyelids are higher. The inheritance of double eyelid genes is a genetic gene, which is actually one or more sex chromosomes in two waiting chromosomes.

If you inherit the double eyelid gene, you will have a double eyelid appearance. Only when the two chromosomes are not inherited without the addition of double eyelid genes, can it appear as a single eyelid.

As older people focus on sagging and cover the overlapping wrinkles, the double eyelids slowly dissipate. There is a certain genetic law between single eyelids and double eyelids, AA and AA represent double eyelids, AA stands for single eyelids, if parents are double eyelids for each other, children are particularly likely to inherit genetic double eyelids. If mom and dad have one eyelid and the other has a double eyelid, the genetics can be full single eyelid or full double eyelid, or even one eye and the other eye double eyelid.

If mom and dad both have a single eyelid, the only chance of inheriting the gene is that it is a single eyelid.

Single and double eyelids are recombined by dominant genes.

controlled, in which double eyelids are genetically controlled, while single eyelids are controlled by genetic recombination. If only one of the parents has double eyelids, the child's double eyelid probability is about 50%, and both parents have double eyelids, then the genetic rate of the child's double eyelids is 100%, and the parents are both single eyelids, so it is not easy to have double eyelid genetic inheritance in the body. However, as children grow up, they sometimes have genetic mutations.

Dad has a single eyelid and mom has a double eyelid, and a child may have a double eyelid, all of which may be a single eyelid.

According to the basic law of molecular genetics, double eyelids are inherited genes, and single eyelids are genetic recombination. The double eyelid inheritance gene can be specifically divided into heterozygous and homozygous. When dad has a single eyelid and mom has a heterozygous double eyelid, the child has half the chance of having a double eyelid and half of the probability of having a single eyelid; When dad has single eyelids and mom is homozygous for double eyelids, the little one must have double eyelids.

Overall, a child has a 3 out of 4 chance of having double eyelids and a 1 in 4 chance of having a single eyelid. The child has single eyelids or double eyelids, which is influenced by genetic inheritance, and parents do not need to be overly anxious. Father's single eyelid and mother's double eyelid, after the baby is born, the probability of double eyelids will be better.

Parents with double eyelids may also give birth to a child with a single eyelid, but it is not possible to look at the parents, but also on the genes of both families. If both men and women have a single eyelid gene in their families, it is possible to give birth to a single eyelid baby at that time, but the maximum probability is only one in four. Even if one party does not have the single eyelid gene, then there will be no single eyelid baby.

It depends on whether the double eyelid is a recessive gene or a dominant gene, if it is a recessive gene, the child has a single eyelid and vice versa.

If one of the husband and wife has one eyelid and the other has two eyes, then the proportion of large eyelids and double eyelids will account for 50% of the child.

There is a high probability that the child has double eyelids.

This can be calculated by yourself, because the double eyelid belongs to the dominant gene, if A is the double eyelid gene, A is the single eyelid gene, then if both parents are double eyelids, the genes of the two people are either AA or AA, and A is the dominant gene, so A and A appear together, showing the characteristics of A. If the human skin reputation gene is AA, it can only be a single eyelid.

So in the first case, the father is AA, and the mother is also AA, and the child gets a gene from the father and a gene from the mother, no matter what, the child is AA, so the child is 100% double eyelids.

In the second case, the father is AA and the mother is AA, and the child gets a gene from the parents, and the child may be AA or AA, and there is still a 100% probability that it is double eyelids.

In the third case, the father is AA and the mother is AA, then as in the previous case, 100% of the genes for double eyelids are displayed.

In the fourth case, the father is AA and the mother is also AA, then the child has three possibilities, AA (25%), AA (50%), AA (25%), so the child has a 25% probability of AA, which shows a single eyelid.

To sum up, only in the fourth case, there is a 25% chance that a baby with a single eyelid will be born, and the rest will be babies with double eyelids. Therefore, the general vertical curvature rate of double eyelid children born to double eyelid parents is very high, but now medical beauty is very developed, if the double eyelids of both parents are obtained by surgery, then it is another matter, after all, surgery cannot change genes, so the above algorithm is only for pure natural parents.

On the other hand, if both parents have a single eyelid, then both of them must be AA genes, then the child can only be AA no matter how they get the genes from both parents, then the child must have a single eyelid. Therefore, parents with single eyelids cannot give birth to children with double eyelids.

I think the child may have double eyelids, or it may be a single eyelid loss, because genes are not easy to say, and there are too many double eyelids of two couples in life, and finally the child is a case of silver pants and single eyelids.

Yes, if both husband and wife have double eyelids, the child will also have double eyelids because the child will inherit the genetics.

It is very likely that double eyelids belong to the dominant gene, both parents are double eyelids, and the probability of inheritance to the child is very large, but it is also possible that the child has a single eyelid.

If one of the husband and wife has a single eyelid and one has two eyes, then the child's eyes may also be a single eye or a double eyelid, because the shirt may be inherited from the father or the mother.

Shuangling Wang eyelid is controlled by Qi Bei's dominant gene, and single eyelid is controlled by recessive base high Wang destruction, which depends on which gene the child inherits, and the baby will change, from double eyelid to single eyelid, and from single eyelid to double eyelid.

A child may have two double eyelids or two single eyelids, one double eyelid and one double eyelid or a single eyelid is possible.
