Why foreigners Europeans are double eyelids 10

Not all foreigners' eyes are double eyelids. Ethnically speaking, the purebred Caucasian and Afrikan races (that is, black and white people) are all characterized by double eyelids, because their eyebrow bones are high and their eye sockets are deep, so when they open their eyes, the place where the eyebrow bone meets the eyelids is folded up, and when the eyes are not so big, it can be found that the eyelids are single-layered.

It has something to do with the shape of their faces... Even if it is a single eyelid, there are wrinkles depending on the shape of the face. It becomes a double eyelid.

Born with genetic problems that have been inherited from generations to generations.

It's like the truth that Koreans basically have a single eyelid.

It's that race, and it's nothing.

First of all, to be correct, as long as we are Chinese nationality, then whether it is double eyelid or single eyelid, it is pure Chinese. Since our country is a comprehensive race country formed by the collection of 56 ethnic groups, so we Chinese generally have a variety of bloodlines, and among these ethnic groups, the largest number is the Han people, according to historical records, the orthodox Han people are generally single eyelids, then from a genetic point of view, if two single eyelid people marry, the offspring born is still single eyelid, so in general, the current double eyelid people are the descendants of our Han and ethnic minorities. Then the reason for the appearance of double eyelids is caused by the following reasons:

1. The beginning of large-scale intermarriages

First of all, in the development process of our China, the opening of large-scale intermarriage activities has gradually developed a lot of multi-ethnic intermarriage offspring, genetic changes have changed the eyelids of these offspring, just like we learned in junior high school, a single eyelid person and a double eyelid person marry, then there will be a 50% chance of double eyelid children, so after the start of large-scale intermarriage, double eyelid Chinese gradually appeared.

2. People with double eyelids are more beautiful

One thing we have to admit is that people with double eyelids may look more beautiful, especially women, women with single eyelids and women with double eyelids stand together, more people will tend to women with double eyelids, so in our ancient times, some princes will marry wives and have children, of course, they will choose more beautiful women, and then the offspring produced with them are more double eyelids.

3. The genes of double eyelids are relatively strong

The last point is that people with double eyelids are generally genetically stronger, simply put, if people with double eyelids and single eyelids get married, then theoretically speaking, there is a 50% chance of giving birth to a single eyelid, but I personally think that the genes of double eyelids are relatively stronger than the genes of single eyelids, because from a macro point of view, there are more and more people with double eyelids, which may also be a result of our people's will.

I have double eyelids, my parents, my daughter. I am also a very pure Chinese, and my previous generations have not even taken a step out of the country. It is decided that both single and double eyelids are dominant recessive genes, and it really has little to do with nationality.

This subject, after reading this question, I can't help but click in and say, how can one eye and two eyes become the standard of whether Chinese or not? A country has its rules, one can be identified from nationality, can also be identified from ancestors, of course, there are many Chinese of such nationality, but this kind of person cannot be identified as pure Chinese!

In fact, no, the normal face shape in my country is basically a national face, and foreigners are also represented by this face shape, and supermodel Liu Wen is also a single eyelid, which is very distinctive.

The Chinese are called the Chinese race or the Asian race, why call them the Mongolian race.

Because their eyebrows are high and their eyes are sunken, they look like double eyelids, which is actually caused by their sunken eyes.

There are two theories on this issue.

The first is that Europeans and Americans do not have Hu blood. In the West, it is generally believed that single eyelids are better than the Hu race.

Another way of saying it is that Europeans and Americans are not without single eyelids. But whether they have single eyelids or double eyelids, they generally have high brow bones and deep eye sockets, so even if they have single eyelids, the eyes are still very deep, unlike the Asian single eyelid effect.

It was a cold time to protect the eyeballs, and there were genes.

Obviously, there is a recessive gene, and only if both parents are carriers of the recessive gene, it is possible to give birth to offspring with a single eyelid If both parents have a single eyelid, the child must have a single eyelid; If the parents have a single and a double, then if the double is dominant (without recessive genes), there must be double eyelids, and if the double is recessive, there is a probability of 1 2 for a single one; If both parents have double eyelids, then only if both parents have recessive genes will have a 1 4 probability of having a single eyelid

The genetics of human beings are the same between different races 99 9, so foreigners must have a single eyelid

Why are you a yellow race, honestly want to do double eyelids, or feel that Wang Shiyong** is doing a very good job.

There are single eyelids.

Difference Between Single and Double Eyelids:

1. The meaning is different:

Single eyelid: The absence of creases in the eyelids is called a single eyelid, commonly known as a single eyelid.

Double eyelids: The upper eyelid has a shallow groove above the eyelid margin, which moves upwards when the eye is opened, and above the sulcus, it slacks and folds down at the double palpebral sulcus.

2. Different forms of presentation:

Single eyelid: The entire upper eyelid is thicker, and the base of the eyelashes is not visible.

Double eyelids: the upper eyelid is thinner, the upper eyelid is not drooping, and the eyelid margin is all visible.

3. Different eyelashes:

Single eyelids: Eyelashes are short, sparse, and tend to slope downwards when looking at eye level.

Double eyelids: The lashes are long and slightly upturned when looking head-up.

4. When the eyes are opened, the orbicularis oculi muscle and the tarsal plate show differently:

Single eyelid: When the eyes are opened, the ** and orbicularis oculi muscles in front of the tarsal plate cannot be lifted with the tarsal plate, so the upper eyelid cannot form a fold appearance.

Double eyelids: When the eyes are opened, the ** and orbicularis oculi muscles below the tarsal line in front of the tarsal plate can be lifted together with the tarsal plate, so that the upper eyelid folds appear.

Single eyelid: <>

Double eyelids: <>

The eyes are the first of the five senses, and the main visual function. Vision plays an extremely important role in people's understanding of the objective world, and it is usually the eyes that obtain information from the outside world90.

It is also an expression organ and a display of the inner world of human beings, which can fully reflect various inner activities such as joy, anger, sincerity, and happiness, so it is called the window of the soul.

It is the most revealing and eye-catching organ in the human appearance, the center of the beauty of the appearance, and is called the window of beauty by estheticians, so a pair of beautiful and perfect eyes often play the role of icing on the cake in the beauty of the human body.

Because from a biological point of view, the single eyelid contains a thicker layer of fat, which can better resist the cold, and most regions in Europe and the United States are colder than Asia, so the single eyelid gradually evolved and slowly passed on to the next generation, so that now Europeans and Americans are basically single eyelids.

European and American double eyelids are mainly due to evolution. They have been growing on that land for a long time, so due to the influence of the local climate, their eyelids have become single.

Because the existence of these two conditions is mainly subject to the environment of the two places, which is the main reason.
