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

So from both paternal and maternal side there will be 50°/•of the probability whether the child is girl or boy.
