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

Answers (1)

Mothers have a pair of X-chromosomes. So they do not play significant role in determining the sex of a new born.
Humans have two sex chromosomes, X and Y.
In females, two X chromosomes are present, making it a perfect pair.
But in males, one is a normal-sized X-chromosome while other is a short Y-chromosome.
In humans, sex of the child is determined by chromosome inherited by the father.
If the zygote inherits X chromosome, the zygote will develop into a female.
If the zygote inherits Y chromosome, the zygote will develop into a male.
All children will inherit an X-chromosome from their mother regardless whether they are boys or girls
