First of all, the eyes
Double eyelids are dominant inheritance. As long as one parent has double eyelids, the chances of a child having double eyelids will be greater, and it looks radiant and shiny. Some babies are born with single eyelids, so parents don't have to worry. You should know that children may become double eyelids before 18 years old.
Second, skin color.
It is often said that "one white covers three ugliness", and the skin color of children is generally the neutralization of parents. If both parents are white, then children will also have white skin; If one parent is white and the other is black, the child will "even" the color of his parents' skin. If the skin on both sides is dark, the child's skin is often not white.
Third, the nose
A tall and big nose is a dominant inheritance. If one parent has a big nose, then the child will inherit it, which will affect the face value.
Fourth, hair.
You know baldness is hereditary, and it is only passed on to men. If the father is bald, then the son born is likely to be the same.
Four, chin, mouth
A big chin and a big mouth is a dominant inheritance. If either parent has these two specialties, they will be passed on to the children, which makes you very helpless!
