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 Fi generation?
[CBSE PMT 2007]
(a) 9:1
(b) 1:3
(c) 3:1
(d) 50:50​

Answer 1

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.

Thus, the correct answer is option D.
