Is there a relationship between the intelligence of the child and the intelligence of the mother?

From the genetic point of view, whether a child is smart or not depends on the mother. Recently, British scientists believe that the genes that determine a child's intellectual development are located on the X chromosome, and the genes on the mother's X chromosome determine the development degree of the child's cerebral cortex, while the father's genes may have an important influence on shaping the emotions and personality types of future generations. According to this theory, it can be explained that boys are prone to "polarization", either extremely intelligent or mentally retarded, while girls are mostly average in intelligence. Therefore, if a woman wants her children to be smart, she doesn't have to find a husband with high IQ, while if a man wants his offspring to have high IQ, he has to marry a smart wife.

Secondly, the mother's cultural quality is closely related to prenatal and postnatal care. The research and analysis of eight maternity hospitals shows that the risk factors of fetal birth defects are closely related to the mother's cultural quality. The higher the mother's educational level, the lower the possibility of fetal defects.
