In Garden Pea, round shape is dominant over wrinkled shape. A pea plant heterozygous for round shape of seed is selfed and 1600 sedds produced during the cross are subsequently germinated. How many offspring will have parental phenotype

A

1600

B

800

C

400

D

1200

Text Solution

Verified by Experts

The correct Answer is:
D
Round shape in pea plant is dominant (R) over wrinkled (r). Pea plant in heterozygous state if self-crossed is shown in cross below

Phenotype=3:1 (round:Wrinkled)
If total 1600 seeds produced during the cross were subsequently germinated. the seeds that would have the parental phenotype will be `1200((3)/(4)xx1600=1200)`.
