What traits of parents are passed on to their children? What is the probability?

1.Eye shape: The influence of a parent's eye shape on a child is obvious.

For children, the shape of the eyes and the size of the eyes are inherited from the parents, and the large eyes are inherited dominantly compared to the small eyes. As long as one of the parents has big eyes, the likelihood of having a child with big eyes will be greater.

Double eyelids: Generally speaking, if a person with a single eyelid marries a person with a double eyelid, the child is most likely to have double eyelids. Therefore, some children are born with a single eyelid and will "fill" the double eyelid like their father when they become adults.

According to statistics, the proportion of double eyelids in infants and young children is only 20%, 40% for middle school students, and about 50% for college students. But if both parents have a single eyelid, the average child will also have a single eyelid.

Eye color: In terms of eye color, dark colors such as black are inherited dominantly compared to light colors. That is, if you envy the blue eyeballs and choose a blue-eyed person to be your lover, but because you are black-eyed, the child born will not be blue-eyed.

Eyelashes: Long eyelashes are also dominantly inherited. As long as one of the parents has beautiful long eyelashes, it is very likely that the child will inherit the long eyelashes.

2.Nose In general, people with large, tall noses and wide nostrils are dominantly inherited. If one of the parents has a straight nose, there is a high possibility of passing it on to the child.

In addition, the nose genetics continue until adulthood, which means that people with short noses when they are young may become tall noses when they reach adulthood. <>

Some characteristics of parents will be passed on to their children, because traits are also related to genes, and if the parents are strong enough genes, they will be passed on to their children.

The characteristics of parents will definitely be passed on to their children, and both men and women have chromosomes that are different to each other, and these chromosomes will be passed on to the child. For example, the simplest double eyelids, single eyelids, this is one of the simplest and most common genetic characteristics.

Some characteristics of parents, of course, will be inherited to children, this is the strength of genes, if parents are very strong, some of the child's physical characteristics and some physical characteristics will be inherited.

Biologically speaking, many characteristics of parents will be inherited to their children, such as double eyelids, whether they have earlobes, and height, which will be inherited to their children to a certain extent.
