Answer 2

$\huge{\bf{\red{Answer♡}}}$

No, mothers have no role in determining the sex of the new born. Mothers have a pair of X chromosome and all children will inherit an 'X' chromosome from thier mother regardless of wheather they are boys or girls. Only presence or absence of y chromosome present in male gamete determines the sex of new born.
