How is the gender of a human child determined?
Gender is determined by specific chromosomes. Women have two X chromosomes and men have an X and a Y chromosome. Due to the male carrying one different chromosome, it is ultimately the father that determines the gender of the unborn baby. If he passes on his X chromosome the child will be female, If he passes on the Y chromosome, the child will be male.
