    In our society the women are often blamed for giving birth to daughters. Can you explain why this is not correct?

    Answer:

    It is not correct to blame the women for giving birth to daughters because a female is a homogametic sex and produces only one type of eggs, each having 22 autosome and one X-chromosome. On the other hand, a male is a heterogametic sex as produces two types of sperms: 50% with X-chromosome and 50% with Y-Chromosome. The sex of baby depends upon the type of sperm fusing with the egg so sex of baby is determined by father and not mother.
