What looks do parents pass on to their children?

　　1. Who do the organs in your body look like?

　　Skin color: always follows the natural law of "multiply and then average", leaving people with no choice. If parents skin If the child is darker, there will never be a child with fair skin; if one child is white and the other is dark, most children will have a "neutral" skin color, and there are also cases where one child is more biased towards one.

　　Eye shape: The child’s eye shape and size are inherited from the parents. Eye Relatively small eyes are dominantly inherited. If one parent has big eyes, the child with big eyes may be older.

　　Double eyelids: Double eyelids are a dominant inheritance. Children with single eyelids and double eyelids are most likely to have double eyelids. But both parents have single eyelids, and most children also have single eyelids.

　　Eye color: Dark colors such as black are dominantly inherited compared to light colors. In other words, children with black eyes and blue eyes will not have blue eyes.

　　Eyelashes: Long eyelashes are also dominantly inherited. As long as one parent has long eyelashes, the child is more likely to inherit long eyelashes.

　　Nose: Generally speaking, a large, tall nose and wide nostrils are dominantly inherited. If one parent has a straight nose bridge, there is a high possibility that this will be passed on to the child. The genetic inheritance of the nose will continue into adulthood. A short nose in childhood may become a tall nose in adulthood.

　　Ears: The shape of ears is hereditary. Large ears are dominantly inherited compared to small ears. As long as one of the parents has big ears, the child will most likely also have big ears.

　　Jaw: It is a dominant inheritance that is not “negotiable”. If either parent has a protruding chin, their children will always have a very similar chin, which is a bit uncanny.

　　Obesity: Children have a 53% chance of becoming obese. If one parent is obese, the probability of the child being obese drops to 40%. This shows that about half of whether one is fat or not can be determined by human factors. Therefore, parents can completely maintain a well-proportioned body shape through a reasonable diet and adequate exercise.

　　Bald: Creator seems to be partial female , so that baldness is only passed on to men. For example, if a father is bald, there is a 50% chance of passing it on to his son. Even the mother's father will pass on a 25% chance of being bald to his grandchildren. This gender genetic tendency, which is passed down from male to female, leaves men helpless.

　　Acne: This facial disease that bothers boys and girls is actually related to heredity. Because if both parents have suffered from acne, the children's incidence will be 20 times higher than those without a family history.

　　Leg shape: The fat-accumulated legs look exactly like those of my parents, and they can be easily exercise And shaped into slender and strong legs. On the other hand, if the legs are too long or too short due to genetics, they cannot be reshaped and can only be left to nature.

　　two. Your height is half and half between your parents.

　　In the past half century or so, due to the development of the entire world economy and the general improvement of population nutrition, the physical growth of children and adolescents has increased year by year, and the onset of puberty has gradually advanced. China's situation is consistent with that of Europe, the United States and other Asian countries. For example, comparing the 1980s and the 1950s in Guangdong, teenagers aged 7 to 18 years old boy The height increased by 8.74 cm and the weight increased by 5.38 kg; the girl's height increased by 6.81 cm and the weight increased by 4 kg. Girls' age at menarche advances by an average of 4 months every 10 years. These objective facts have naturally led to higher height requirements among teenagers and parents in recent years than before.

　　It is said that 70% of parents' genetics are the main factor in determining a child's height, because 35% of the factors that determine height come from the father and 35% from the mother. If both parents are not tall, then it depends on the baby's 30% effort.

　　Therefore, the saying that the father is shorter and the mother is shorter is not necessarily correct!
