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 their progenies? (1)9:1 (2)1:3 (3)3:1 (4)50:50

Answer 1

Answer:

The yellow seeds are dominant to green seeds. The heterozygous yellow seeded plant will have the genotype Yy and the green seeded plant will have yy. If these two plants are crossed, the result of F1 generation will be two Yy (yellow seeds) and two yy (green seeds). The probability of the offsprings will be 50:50.
