Best ResponseYou've already chosen the best response.2then i suppose it's A. if the allele is Xlinked, then there will be two recessives. one on the Y and it's link on the X. two recessives will always exhibit the trait in question

Best ResponseYou've already chosen the best response.2OK. Males are XY and females are XX. If the baby is a boy, it means he inherited the Y from his dad. He could have got either of his Mom's two X chromosomes. It means that even if the allele on the X is recessive the baby boy will express it because the Y does not have any alleles on it, dominant or otherwise.

Best ResponseYou've already chosen the best response.2so i guess my explanation was somewhat wrong but the answer was right?

Best ResponseYou've already chosen the best response.2"Wrong" is not a word we use on OpenStudy, Saso, but yeah. Pretty much. :/ You and your luck with genetics problems. Like finding that solution to my challenge back in January that I didn't think of when I came up with it.

Best ResponseYou've already chosen the best response.2Process of elimination is pretty efficient on this one, rather than trying to logic it out by brute force. It says the allele from Mom is recessive. If the boy got a dominant allele for the same gene from Dad, the recessive allele would definitely NOT be expressed. So it cannot be D. The allele cannot skip a generation and be expressed in at the same time. So it cannot be C. His mother's father probably did exhibit the trait. But that gives no info on whether it is dominant or recessive, so it's not B. A is the only one left standing.
