Question
When RRYY (round yellow seed) pea plant is crossed with rryy (wrinkled green seed) pea plant, what will be the genotype of F₁ generation and in dihybrid cross what will be the phenotypic ratio in F₁ generation?
Answer
When RRYY (round yellow seed) pea plant is crossed with rryy (wrinkled green seed) pea plant, the genotype of F₁ generation will be RrYy (round yellow seed).
In dihybrid cross of RrYy x RrYy, the phenotypic ratio in F₁ generation will be 9:3:3:1, where 9 individuals will have round yellow seeds, 3 individuals will have round green seeds, 3 individuals will have wrinkled yellow seeds and 1 individual will have wrinkled green seeds.
