Hello,
As we know that the chromosomal sex pattern in female is XX and in male is XY.
50% of the allele is provided by male and 50% by female.
When the fusion of male and female Gametes takes place then either XX will be formed or XY will be formed.
So it will be indeed a father and not mother who is responsible for the sex of the child.
Because mother have same sex chromosomes , so if father gives X then when Combined with mother sex chromosome it will be XX i.e. a baby girl will born. And if father gives Y and combines with mother sex chromosomes then it will be XY i.e. a baby boy will be both.
Hope it helps!
