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 would you expect in F1 generation ?

Question

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 would you expect in F1 generation ? (A) 9: 1 (B) 1: 3 (C) 3: 1 (D) 50: 50

Yellow (Y) seeds are dominant to green (y). So a heterozygous yellow seeded plant will have the genotype of (Yy) and a green seeded plant will have genotype of (yy). When these two plants are crossed, the F1 generation will have the ratio of yellow: green as 50: 50. It is

Q. 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 would you expect in $F_{1}$ generation ?

9 : 1

1 : 3

3 : 1

50 : 50
