Question

If an egg is fertilized by a sperm, with an x chromosome, the united single cell will develop into a baby girl?

x+y= a baby boy
x+x= a baby girl
?

Answer 1

Yes. That's why it's the sperm that decides the gender of a child, because females have two x chromosomes so they can only pass on x chromosomes and males have an x and a y.

Answer 2

yes.
