Red-green color blindness is inherited as an x-linked recessive (xc). if a color-blind man marries a woman who is heterozygous for normal vision, what would be the expected phenotypes of their children with reference to this character? in your answer, specify in your phenotype descriptions the gender of the children. (for example, don’t just say 75% of the children would be colorblind – you would instead say 100 % of the daughters would be colorblind and 50% of the sons would be colorblind. note that this is not a correct answer; it is just to give you an idea of how to explain the correct phenotypes of the cross.)
