#Section 3: Genetics, Cellular and Molecular Biology
Mendel crossed plants with the seed characters round and yellow with plants having the contrasting seed characters wrinkled and green. Round is dominant
to wrinkled, and yellow is dominant to green. The F1 progeny were all round and yellow. What will be genotype ratio in F2 generation?
