ANSWER THIS QUESTION AND YOU GET BRAINLIEST AND A THANKS In humans, as well as in many other animals and some plants, the sex of the individual is determined by sex chromosomes. The sex chromosomes are one pair of non-homologous chromosomes: XX represents a female, while XY represents a male. When a gene for a specific trait is attached to the X or Y chromosome, we say it is sex-linked, and when it is attached to the X chromosome, we say it is X-linked. Alleles for these linked traits, such as hemophilia or color blindness, crosses, may be recessive or dominant.

Hemophilia is an X-linked, recessive trait. The recessive allele for hemophilia is actually a mutated version of the normal alllele but it can still be passed on through generations. Imagine a female is a carrier for hemophilia; her genotype is XHXh. She is married to a man who does not have hemophilia. What conclusion is NOT valid concerning this genetic cross?

A) 0% of female offspring will have hemophilia.
B) 100% of the male offspring will have hemophilia.
C) There is a 50% chance that male offspring will have hemophilia.
D) The chance that female offspring will have the allele for hemophilia is 50%.
