Question

In a cross between round yellow seeds (RRYY) and wrinkled green seeds (rryy) of pea plants, what is the ratio of plants obtained in F2 generation?

Answer 1

Answer:

When the given parental plants (with genotype RRYY and rryy) are crossed, they will produce RrYy (Round yellow offsprings) in the F1 generation. Now parents with genotype RrYy will interbreed and produce phenotypes in the ratio 9:3:3:1 and genotypes in the ratio 1:2:1:2:4:2:1:2:1 in the F2 generation.

Answer 2

When the given parental plants (with genotype RRYY and rryy) are crossed, they will produce RrYy (Round yellow offsprings) in the F1 generation. Now parents with genotype RrYy will interbreed and produce phenotypes in the ratio 9:3:3:1 and genotypes in the ratio 1:2:1:2:4:2:1:2:1 in the F2 generation.
