Excluding factors such as acquired education as well as nutrition, the genetic predisposition to intelligence is about 50% to 60%, which is mainly related to the mother’s genes, although it is not absolute and varies from person to person. It is understood that the amount of intelligence is related to many different factors, which may be affected by the growing environment, nutrition, and education and other acquired factors, but it is mainly related to genetics. According to research, the genetic influence on intelligence is around 50% to 60%, with the more important being the mother’s genes. This is mainly because the genes related to intelligence in human beings are mainly concentrated on the X chromosome, and mothers have 2 X chromosomes, while fathers only have 1, so the mother’s intelligence will occupy a more important position in the inheritance. However, this is not absolute, intelligence genes, although very important, but can be cultivated through the later to improve intelligence, specifically including timely supplementation of nutrition, to enhance the child’s hands-on ability and so on.
