Red-green color blindness in humans is caused by a recessive allele located on the XX chromosome. Figure 1 shows the potential offspring of a female who is red-green color-blind and a male with full-color vision. All of the possible male offspring would be color-blind, and all of the possible female offspring would have full-color vision.If during the production of male gametes an error in meiosis occurred, sperm containing both an XX and a YY chromosome could be produced.Figure 1. Possible offspring of a female who is red-green color-blind and a male who has full-color vision.How would the extra chromosome affect the male offspring produced by the gamete?ANone of the potential offspring would be male, because the potentially male zygote would have two XX chromosomes, and the YY chromosome would be ignored.BThe male offspring would all be red-green color-blind, because of interference from alleles on the YY chromosome.CThe male offspring would have full-color vision, because of the presence of the extra XX chromosome.DThere would be no change to the phenotypes of the possible offspring, because the extra XX chromosome would not be active.
