Consider three genes: X, Y, and Z. The X and Y genes are on the same chromosome; gene Y is on a different chromosome. An organism is heterozygous for all three genes. The cell’s parents were both homozygous for all three genes. This organism produces a gamete with the dominant X allele. Which of the following is true of this gamete? A. It is likely to have both the dominant Y and Z alleles. B. It is likely to also have the dominant Y allele but not necessarily the dominant Z allele. C. It is likely to also have the dominant Z allele but not necessarily the dominant Y allele. D. It is not more likely to have either the dominant Y or dominant Z alleles.
