Whose genes do boys generally inherit

People often say that genes are strong. Generally speaking, it describes that parents pass on most of their own characteristics to their children. There is also a saying among the people that daughters look like their fathers and boys look like their mothers. In fact, this statement has some basis, but it does not apply to everyone. What a child looks like is mainly determined by the genes of both parents. The following is some relevant knowledge for you.

1. Absolute inheritance

Skin color: leaving people with no choice. It always follows the natural law of neutralizing colors of the parents. For example, if the parents have dark skin, they will never have children with fair skin; if one parent is white and the other is black, then after averaging the skin color during the embryo, the children will most likely have a neutral skin color that is neither white nor black, but there are also cases where the skin color is more biased towards one parent.

Jaw: It is a dominant trait that cannot be negotiated, and you are helpless about it. For example, even if one of the parents has a prominent large chin, the children will often have a similar chin without exception, which is somewhat uncanny.

Double eyelids: also absolutely hereditary. Interestingly, most of the father’s double eyelids will be passed on to his children. Some children are born with single eyelids, and then they grow up to have double eyelids like their fathers. In addition, big eyes, big earlobes, high nose bridge, and long eyelashes are the most characteristic features that can be inherited from parents.

2. More than half of the probability of inheritance

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

Baldness: The Creator seems to favor women and only allows baldness to be passed on to men. For example, if the father is bald, there is a 50% chance that the trait will be passed on to his son. Even the mother's father will leave a 25% chance of baldness to his grandchildren. This gender inheritance tendency of being passed down to males but not females leaves men helpless.

Acne: This facial disease that worries young boys and girls is actually related to genetics. Because if both parents have suffered from acne, their children's incidence rate will be 20 times higher than those with no family history.

3. Low probability of inheritance

Gray hair: This is a recessive inheritance with a low probability, so you don’t have to worry too much about your parents’ premature graying of hair on their children’s heads.

4. Inheritance of acquired plasticity

Voice: Usually boys' voices are like their father's in terms of volume and pitch, while girls' voices are like their mother's. However, if the voice quality, which is influenced by the inheritance of the parents' physiological and anatomical structure, is not beautiful, it can usually be changed through acquired pronunciation training. This allows people who do not have favorable vocal conditions to realize their dream of having a sweet voice through scientific and hard practice.
