A. a guy receives an X from the mother who has 2 X's and a Y from the dad who has both an X and a Y. women get an X from both mom and father, and for the reason that the dad has in reality one to bypass on, it has to incorporate the X-proper allele. this suggests all his daughters receives it.

Think about it.

Men have two sex chromosomes: X and Y.

When they produce sperm, each sperm gets half of their genetic complement. So half of hte sperm get X chromosomes, and half get Y chromosomes.

Women have two sex chromosomes: X and X.

Mom's eggs each get half of mom's chromosomes, half get X and half get the other X.

So, when a sperm and an egg meet, each contributes one sex chromosome.

Now, think about your question again: If mom's eggs always have an X, and a person with XY is a son, and a person with XX is a daughter, then the father passed on the X-linked trait to which child?

Daughters because the Y is passed on to the male offspring.
