When Mendel crossed true-breeding tall pea plants with true-breeding short pea plants, all the offspring were tall. Then he allo
wed 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.
by injecting the weakened virus into your body it helps the body familiarize and create the right antiviruses for the virus so that if it ever gets in your system you can actually fight it.
