The shape and size of children's eyes are inherited from their parents, and big eyes are dominant over small eyes. If one of the parents has big eyes, then his eyes are more likely to be big. Interestingly, most fathers leave their double eyelids to their children. Some children are born with single eyelids, and when they grow up, they will have double eyelids like their father. In addition, big eyes, big earlobes, high nose and long eyelashes are the most characteristic inheritance that can be obtained from parents when the five senses are inherited.
Second, skin color.
Let people have no choice. It always follows the natural law of neutral colors on parents. For example, parents with dark skin will never have children with white skin; If one side is white and the other side is black, then most children will be given neutral skin color that is neither white nor black during the embryonic period, but there are also cases that are more biased towards one side.
Third, the nose
Generally speaking, the nose is big and tall, and the nostril width is dominant. If one of the parents has a straight nose, it is more likely to be passed on to the child.
Fourth, the chin
The mandible is a non-negotiable dominant inheritance, which makes you helpless. For example, even if either parent has a prominent chin, children often have similar chins without exception, which is a bit bizarre.
Half of the following factors are determined by heredity!
Height: Only 30% of the initiative is in your hands, because 35% of the factors that determine height come from father and 35% from mother. If both parents are not tall, then the acquired height factor is only 30%, which also determines that your attempt to grow up will not have obvious effect.
Obesity: Children will have a 53% chance of becoming obese. If one parent is obese, the probability of children being obese will drop to 40%. This shows that about half of being fat can be determined by human factors. Therefore, parents can make their posture symmetrical through reasonable diet and adequate exercise.
Baldness: the creator seems to favor women and let baldness be passed on only to men. For example, if the father is bald, the probability of passing it on to his son is 50%, and even the mother's father will leave his 25% probability of baldness to his grandchildren. This sexual genetic tendency of passing on men but not women makes men very helpless. (manually distressed little prince)
Acne: This facial disease that worries both boys and girls is actually related to heredity. Because if both parents have suffered from acne, the prevalence rate of children will be 20 times higher than that of children without family history.
