In our society a woman is often blamed for not bearing male child. Do you think it is right ? Justify.
$50$ per cent of sperms carry the $X$-chromosome while the other $50$ percent carry the $Y$. After fusion of the male and female gametes the zygote would carry either $XX$ or $YY$ depending on whether the sperm carrying $\mathrm{X}$ or $Y$ fertilised the ovum.
