Question

In pea plants, purple flowers (P) are dominant over white flowers (p). If two heterozygous purple-flowered plants are crossed with each other, then what are the possible genotypes of the offspring?
A) Pp only
B) PP and pp
C) Pp and pp
D) Pp, PP and pp

Answer 1

Answer: Option D Pp,PP and pp

Explanation:

• Heterozygous plants are the ones which carry two different alleles, one dominant and the other recessive.

• Thus, the genotype for the purple flowered heterzogyous individuals would be Pp.

• If these are crossed together, Pp X Pp——————> PP, Pp, Pp, pp

• Thus, from the given cross the different possible genotypes for the offsprings comes out to be PP, Pp and pp.

There is a Punnett square representation for the cross attached for reference.

Answer 2

The answer is D) Pp, PP, and pp.

i attached a picture of a punnett square i did to help you understand the answer more, if you want.
