Question 27
Do the genetic combination of mothers play a significant role in determining the sex of a newborn?

Answer 1

No, the genetic combination of mothers doesn't play a significant role in determining the sex of a newborn because mothers have a pair of X-chromosomes. All children will inherit an ‘X’ chromosome from their mother regardless whether they are boys or girls. A newborn who inherits an ‘X’ chromosome from father will be a girl and one who inherits a ‘Y’ chromosome will be a boy.
