Why is my right eye always on a single eyelid? The left eye is a double eyelid

No way, so do I, just cut the single one in two.

Me too, so I wore a double eyelid patch on my right eye for two years, and now it's really a double eyelid.

Normally, so do I, as I get older, the single eyelid will become a double eyelid, and the age of the change is different for different people.

It's normal, just like some people have one big eye and one small eye.

Some people have double eyelids in one eye and single eyelids in the other, and there are two different types of such people, one is single eyelid in the left eye and double eyelid in the right eye. One is a double eyelid on the left eye and a single eyelid on the right eye. According to the theory that yin and yang have their own control over the left and right brains, the former is more vigorous than yang, and its behavioral characteristics are dominated by the left brain.

The latter is more vigorous than yang, and its behavioral characteristics are dominated by the right brain. There is also a type of person, the inner double eyelid, the eye feature of this type of person gives the impression of a single eyelid, but after closer inspection, you will find that the characteristics of their inner double eyelid will appear between the closing and the open closing of the eye. Therefore, this kind of person is also more developed in both the left and right brains, but the right brain is the main one.

In fact, single or double is determined by the genes of the parents, and the double eyelid is controlled by the dominant gene, that is, the genotype AA or AA determines the double eyelid; Single eyelid is controlled by recessive genes, i.e., genotype AA determines single eyelid. The production of single eyelids and double eyelids is related to one of the levator palpebrae muscles in the upper eyelid. The formation of double eyelids is due to the fact that the levator palpebrae muscle has fibers extending to the subcutaneous area, and the muscle contraction causes the retraction of the attachment site, constituting the **fold, that is, the double eyelid, commonly known as double eyelids; The single eyelid lacks this levator palpebrae fiber, which attaches to the **, and therefore does not have a fold.

If a person's genotype contains the dominant gene A that controls double eyelids, his trait performance should generally be double eyelids. However, in the process of ontogeny, due to the modification of other genes or the influence of complex factors such as internal and external environmental conditions, it may lead to incomplete development of levator palpebral muscle fibers, which may lead to one eye with one eyelid and the other eye with double eyelids.

Others show double eyelids at one stage and single eyelids at another.

1. Eliminate the influence of complex factors such as internal and external environmental conditions, and only consider the role of genes

1 2: Because the single eyelid is recessively inherited, then because a single eyelid child is born, so the couple's traits are AA, AA, then the probability of having another child is 1 2

It's normal, just like some people have one eye big and one small, if you want to become a double eyelid, you can achieve it by cutting the double eyelids, which is minimally invasive and traceless.

Why do you put Brother Pig's bright **?

A single pair is a different internal structure of the eyelids.

Double eyelid surgery can be done.

Genetic problems, don't worry too much, just be healthy!!

Maybe it's a genetic problem, it's normal. This is a random match of the genes themselves

Just like the boy in Nuo Cao Li, the second Kim Young-gwang, a single pair, super obvious!

Actually, this is very normal, don't mind too much.

Why are people's eyes different in size? And some eyes have a double eyelid and a single eyelid? This one.

Internal problems may have something to do with genetics, I wasn't very good at biology when I was in school, and I only felt amazing about heredity, and I don't know why it was so amazing.

However, have you ever noticed that people are not only different in the size of their eyes, but also in pairs of organs such as two ears, two nostrils, two eyebrows, and even two arms, two legs, two hands, and two feet. The size, shape, and appearance look the same, but it's really different, and you can always find a thousand differences. That's where the magic comes in.

As for double eyelids and single eyelids, I just remember that it was as if the problem of dominant and recessive was talked about in biology class when talking about chromosomes. Anyway, when dad and mom x and y are matched, it's what the arrangement and combination are like, and we can't choose. Hehe, just kidding.

And a person's eyes may have double eyelids today, and become single eyelids tomorrow because of crying, right?

You may not be able to find two of the leaves that fall from the tree that look exactly the same, maybe this is the only way to make this life so colorful!
