Inheritance from my family?

If you maternal grandfather is “dome” bald and your maternal uncle has the same appearance, but his maternal grandfather is not bald: does that mean such gene was inherited through the Y chromosome? Therefore, will my mother carry that on her X chromosome to me?

There is a 50/50 percent chance that you will get the genes from your mother’s or father’s side of the family. By the age of 26, you might know who you take after. Look through a lot of photos of uncles and grandparents and see if you can identify yourself.
