Do genetic combination of mothers play a significant role in determining the sex of a new born?

Answer in Brief

Solution

Mothers have two X chromosomes as sex chromosomes so, they produce eggs with X chromosome. All of her children (both girl and boy) receive X chromosome from their mother. So, genetic combination of mothers do not play a significant role in determining the sex of a new born.
