In our society the women are often blamed for giving birth to daughters.

Can you explain why this is not correct?

Human being contain 23 pairs of chromosomes, human males having 22 pairs of autosomes and containone or two types of sex chromosome. i. e. either X or Y. Whereas human females have 22 pairs of autosomes and only one type of sex chromosome i.e, the X sex chromosome. Hence the sex of an individual is determined by the type of male gamete ( X or Y) fuses with female sex gamete (X). If the fertilizing sperm contains sex chromosome X then baby girl will be born and if the fertilizing sper contains Y sex chromosome the baby boy will be born. Hence it is wrong and incorrect to blame a woman for giving birth to daughters.
