Question

Does genetic combination of mother play a significant role if determining the sex new-born body?

Answer 1

• The sex of an individual depends on the combination of sex chromosomes in its cells, that is, the combination of X and Y chromosomes.
• An embryo with XX genotype would develop into a female whereas, an embryo with XY would develop into a male.
• The mother produces a gamete with the X chromosome.
• The father produces half gametes carrying an X chromosome and half carrying a Y chromosome.
• The sex of the embryo or the child in humans is determined by the father whereas, the genetic combination of mother does not play a role in determining the sex of the new-born baby.
