Purple petal color in pea plants is dominant to white petal color. two heterozygous pea plants are crossed. determine the genotype of the offspring.

(answer choices are shown)

1. DD

2.Dd

3.Dd.

4.dd

Explanation:

there you go

The genotype of the offspring would be DD, Dd, Dd, and dd.

From the illustration, the allele for petal color is represented by D or d depending on dominance/recessive respectively.

Purple color is dominant (D) over white color (d). Thus, a heterozygous pea plant would have the genotype Dd.

Now, two heterozygous plants are crossed:

                 Dd     x     Dd

               DD    Dd    Dd    dd

Hence, the genotype of the offspring would be DD, Dd, Dd, and dd
