In our society the women are often blamed for giving birth to daughters Can you explain why this is not correct?
All human beings have $23$ pairs of chromosomes. Human males have $22$ pairs of autosomes and contain one or two types of sex chromosome. They are either $\mathrm{X}$ or $\mathrm{Y}$. On the contrary, human females have $22$ pairs of autosomes and contain only the $X$ sex chromosome. The sex of an individual is determined by the type of the male gamete ($X$ or $Y$ ), which fuses with the $X$ chromosome of the female. If the fertilizing sperm is $X$, then the baby will be a girl and if it is $\mathrm{Y}$, then the baby will be a boy. Hence, it is incorrect to blame a woman for the gender of the child.
