In pea plants, yellow seeds are dominant to green. If a heterozygous yellow seeded plant is crossed with a green seeded plant, what ratio of yellow and green seeded plants could you expect in F ₁ -generation.

Step-by-step solution

Yellow seeds are dominant is green (Y). So, a heterozygous yellow seeded plant will have the genotype of ( Y , y ) and a green seeded plant will have genotype (yy). When these plants are crossed, the F ₁ -generation will have the ratio of yellow : green as 50 : 50 .
