Why do some people encounter social interaction, why do people like to participate in social activities to make friends, but some people avoid it?Some researchers suggest that people with the higher C.D.38 gene expression as high as possible in C.D.157 gene sequences are more likely to socialize than others
The C.D.38 and C.D.157 genes control the secretion of oxytocin
these two genes affect a person's social abilities.But opponents argue that a person's social abilities are determined by oxytocin on chromosome 4. Both male and female brains can synthesize this hormone, which has an important effect on a person's social abilities.
