Answer:the sex of a child is decided as the zygote is formed by the fusion of sperm and ova

• females possess XX sex chromosome while the males possess XY sex chromosome
• as a result, males produce 2 types of sperms - 50% containing X chromosome and 50% Y chromosome
• now, if the sperm containing X chromosome fertilizes an ova then the offspring formed will be female
• and if the sperm containing Y chromosome fertilizes an ova then the offspring formed will be a male
• scientifically, sex of a child is determined by father and not by mother
