Because human intelligence-related genes are mainly concentrated on the X chromosome, while women have two X chromosomes and men have only one, the mother's intelligence plays a more important role in genetic factors.
Appearance: Father is older than mother. American psychologist Christenfield explained that a baby's face may look more like his father because of the genetic characteristics that the father passed on to the child.
This is also a manifestation of human instinct of "self-protection", because there is no doubt about who is the mother and who is the father, so it is beneficial for the baby to be like the father, which can urge the father to cast more fatherly love.
Height: Mother is older than father. According to experts in Hong Kong, they studied 65,438+000 male and female babies selected from health centers.
By measuring the height regularly, it is found that the height growth of babies after 3 years old is significantly related to the height of their parents. In the case of good nutrition, parents' heredity is the main factor to determine the height difference of children, especially the height of mothers, so most children with high mothers grow tall.
Personality: Father is older than mother. Generally speaking, mothers often influence their children with feminine qualities such as delicate feelings, careful work and gentle temperament, while fathers express their children with masculine qualities such as courage, perseverance, tenacity and charm. Therefore, the formation of a child's complete personality depends on the joint efforts of both parents. But the role of fatherly love has a greater influence on daughters.
A psychologist in new york believes that a father can teach his daughter many important lessons and experiences in life, and make her character more colorful.
