Answer:
The chromosomes in the reproductive cells of female be 22pairs + XX
The chromosomes in the reproductive cells of male be 22 pairs + XY
Gametes are formed due to meosis in case of both male and female having half the number of chromosomes. So,
The contribution of the mother is always X irrespective of whether the baby is boy or girl. Sex of the child is determined by father and not the mother. If the X sperm fuses with the egg then the child is female and if the Y sperm fuses with the egg then the child is boy
