Heredity is a phenomenon that exists in everyone. Some children directly inherit the characteristics of their parents, while some children inherit the characteristics of their grandparents from the previous generation. Of course, for most children, the main inheritance is from their parents. For example, a child's height is inherited from both parents, intelligence is inherited from the mother, and personality is inherited from the father. Below, I will give you a detailed introduction to genetics. 1. Whose genes influence height? The parents each take half. Under the premise of nutritional conditions, 70% of the initiative of a child's height is in the hands of his parents. The parents' genetics are the main factor determining the child's height, because 35% of the factors that determine height come from the father and 35% from the mother. If both parents are short, then it depends on the baby's 30% acquired efforts. 2. Whose genes are more responsible for intelligence? A mother's intelligence is somewhat hereditary, but is also influenced by acquired factors such as environment, nutrition, and education. According to scientists, genetics accounts for about 50%-60% of the influence on intelligence. In terms of genetics, if the mother is smart, the child she gives birth to will mostly be smart. If it is a boy, he will be even smarter. The reason for this is that the genes related to human intelligence are mainly concentrated on the X chromosome. Women have two X chromosomes and men only have one, so the mother's intelligence plays a more important role in heredity. 3. Whose genes influence personality more? dad. Personality is largely inherited from the father. The formation of personality certainly has innate components, but it is mainly influenced by later factors. Comparatively speaking, father's influence is greater than mother's. Among them, the role of fatherly love has a greater impact on daughters. A psychologist believes: "Fathers play an important role in the formation of their daughters' self-esteem, sense of identity and gentle personality." Another expert suggested that fathers can teach their daughters many important lessons and experiences in life, making their daughters' personalities more colorful. 4. Whose genes are more responsible for appearance? Skin color: It always follows the natural law of “multiplication and then averaging”, leaving people with no choice. If the parents have darker skin, they will never have children with fair skin; if one parent is fair and the other dark, the children will most likely have a "neutral" skin color, but there are also cases where they are more biased towards one side. Eyes: (Eye shape) A child’s eye shape and size are inherited from his or her parents. Big eyes are dominant over small eyes. If one of the parents has big eyes, the likelihood of having a child with big eyes is higher. (Double eyelids) Double eyelids are dominant traits. A baby born to a parent with single eyelids and a parent with double eyelids is very likely to have double eyelids. But if both parents have single eyelids, the children will generally also have single eyelids. Nose: Generally speaking, a large, high nose with wide nostrils is a dominant trait. If one of the parents has a straight nose, there is a high chance that it will be passed on to the child. The genetic genes of the nose will continue into adulthood. A short nose in childhood may become a high nose in adulthood. Ears: The shape of the ears is hereditary, with large ears being dominant over small ears. If one of the parents has big ears, the child is very likely to have big ears as well. |
