How is the sex of the child determined in human beings?
In organisms, a specific pair of chromosomes determine the sex of the individual called sex chromosome. In human beings, sex is determined by the XX-XY chromosomes. Females contain XX chromosomes and males contain XY chromosomes.
So, if the male gamete X chromosome fuses with the female X chromosome then the child will be female or when male gamete Y fuses with the female X chromosome then it will be the male child.
