If society blames the mother for the birth of a girl, what is the most scientific response?

Answer and explanation

Correct answer: The mother always contributes an X chromosome, while sperm type creates the sex-chromosome difference

For the usual human XX–XY pattern, every egg carries X, whereas sperm may carry X or Y. Fertilisation with an X-bearing sperm generally produces XX, and fertilisation with a Y-bearing sperm generally produces XY. Thus blaming the mother for giving birth to a girl is scientifically unjustified. The result is a biological outcome of fertilisation, not a choice or fault of the mother.
