When Mendel crossed true-breeding tall pea plants with true-breeding short pea plants, all the offspring were tall. Then he allowed the first generation tall plants to self-pollinate.
What were the expected ratios of phenotypes in the F2 generation?
o A. Because this is a monohybrid cross of pea plants that carry two alleles for plant height, the expected ratio is 3 tall : 1 short.
B. Because this is a dihybrid cross of pea plants that carry three alleles for plant height, the expected ratio is 9 tall: 3 intermediate: 1 short.
C. Because this is a dihybrid cross of pea plants that carry four alleles for plant height, the expected ratio is 4 tall: 1 short.
D. Because this is a monohybrid cross of pea plants that carry two alleles for plant height, the expected ratio is 1 tall: 1 short.
