Do most of my daughter's genes follow her father or mother?

Introduction: In our daily life, we often hear a sentence: daughters follow their fathers and children follow their mothers. Most people think that daughters are more like fathers in character and appearance, while sons are more like mothers, especially when babies are young. But this statement is not entirely correct. Next, Bian Xiao will analyze whether most of the baby's genes are inherited from the mother or the father.

First, the baby's height problem is often heard: Dad is short and short, and Mom is short and short. This statement means that the height of the mother has a great influence on the height of the child, but in fact this statement is incorrect. Genetic factors from both parents account for only about 1/3 in infants. The heritability of the height of both parents is half, and the acquired factor accounts for 2/3. For example, nutrition can not keep up, sleep, exercise and so on. Therefore, apart from genetic factors, the biggest influence of baby's height comes from acquired factors. Therefore, parents who are not tall enough, if they want to have a tall baby, can supplement nutrition to their baby from an early age and give full play to acquired factors.

Second, the baby's intelligence problem has been studied by British scientists. It shows that the gene fragment of the child's intellectual development is on the X chromosome, so the gene on the mother's X chromosome determines the degree of the baby's brain development, while the father's gene is more about shaping the child's later personality and mood. Although the baby inherits the mother's intelligence, the influence of heredity on intelligence accounts for about 50~60%, so nurture is more important. Dad plays a great role in shaping children's later character. A responsible father can cultivate a strong baby, especially the father plays a great role in the formation of a girl's character.

Third, the baby's appearance The baby's appearance is mostly determined by genes, such as eyes, nose and eyelashes, which are all dominant genetic inheritance. When one parent has a single eyelid and the other has a double eyelid, then the baby has a greater chance of having a double eyelid. If both parents have single eyelids, then the baby usually has single eyelids. Baby's eye size is inherited from parents, so when one of the parents has big eyes, the child with big eyes will be bigger; The size and width of the nose are also given by parents. At this time, we should pay attention to the collapse of the baby's nose, which cannot be shaped the day after tomorrow. The shape of ears and the length of eyelashes are inherited, and baldness is generally only passed on to male babies at home.
