Normal growth of oats dominates over gigantism, and early maturity dominates late maturity.

Normal growth of oats dominates over gigantism, and early maturity dominates late maturity. Determine the probability of appearance in the offspring of giant late-ripening plants from crossing plants heterozygous for both traits.

Normal growth – AA, gigantism – aa, early maturity – BB, late maturity – cc.
Parents will have the genotype AaBb
P AaBv x AaBv
G AB, AB, AB, AB
F1 Using the Punnett lattice, we find:
1ААВВ: 2ААВв: 1ААВв: 2АаВВ: 4АаВв: 2Аавв: 1ааВВ: 2ааВв: 1аavв.
HAP – 1: 2: 1: 2: 4: 2: 1: 2: 1
FAP – 9: 3: 3: 1.
Among them, there will be 1/16 or 0.0625 giant late-ripening plants.
