Since the Y-Chromosome is only passed from father to son, shouldn't kids take the fathers last name?

Sex Chromosomes for parents: Dad - XY MOM: XX Each parent can only give his or her offspring one sex chromosome. Assuming you are genetically normal, you are either XX (girl) or XY (boy). If you are a boy, your sex genotype is XY, so you received one X chromosome from you Mom and one Y chromosome from your Dad.

You can't receive an X chromosome from your Dad because that would make you a girl (since your Mom can only give you either of her two X chromosomes). However, you are a boy, so if you get your mom's genetic trait, then that means that it is X linked. (This is kind of complicated to know because most X-linked diseases are recessive, and that means that for girls to express the mutation, they need to inherit two X chromosomes from their mom and their Dad at the same time which are affected, which is unlikely.) X-linked traits: Passed on from the mother to the son.

Y-linked traits: Passed on from father to the son. Remember, if you are a boy, you are XY, and if you get your Dad's trait it had to come from his Y chromosome. He can't give you a X because that would make you a girl, where the case in point is that you are a boy.

I cant really gove you an answer,but what I can give you is a way to a solution, that is you have to find the anglde that you relate to or peaks your interest. A good paper is one that people get drawn into because it reaches them ln some way.As for me WW11 to me, I think of the holocaust and the effect it had on the survivors, their families and those who stood by and did nothing until it was too late.
