In dihybrid crosses of heterozygous parents, the ratio 9:3:3:1 indicates ___. a. codominance c. incomplete dominance b. independent assortment d. three alleles for each trait For the next four questions, use the following key: a = All the offspring will exhibit the dominant trait. c = The recessive trait will show up in about 50% of the offspring. b = All the offspring will exhibit the recessive trait. d = The dominant trait will show up in about 75% of the offspring. What will be the result if: 9. Bb mates with bb? 10. BB mates with bb?
