Color blindness is an X-linked recessive trait. An XX female can be colorblind in one eye due to random X-chromosome inactivation. Is it possible for a male to have different color-blindness phenotypes in each eye? O a. No, since trisomy of the sex chromosomes is lethal O b. Yes, in an XXY male with a different active X in each eye OC. No, since XXY males inactivate both X chromosomes O d. Yes, in an XYY male where each eye has alternate Y inactivation O e. No, males always have XY sex chromosomes so they will express whatever single X-linked allele they possess
