Solution
The correct option is A Paternal genetic influence
Paternal genetic influence is when a phenotype results from the genotype of the father, rather than the genotype of the mother. The gender of the child is determined by the father because the father's genotype is XY and that of the mother is XX. When the Y chromosome of the father fuses with the X chromosome of the mother the child will have a genotype XY and it will be a boy. When the X chromosome of the father fuses with the X chromosome of the mother the child will have a genotype XX and it will be a girl. Hence the father is responsible for the gender of the child. This was explained by the doctor to Sita's mother in law, so she stopped accusing her of having daughters. Thus the correct answer is option A.
