Question

Find out genotype of violet coloured flower ?

Answer 1

Answer:

if the offspring produced by the test cross is 50% purple and 50% white flower then the genotype of the purple flower pea plant is heterozygous dominant (Pp). If all the flower produced is purple coloured then the genotype of the purple flower is homozygous dominant (PP).

Answer 2

Explanation:

The cross between violet-flowered plant and white-flowered plant:

Vv (violet) X vv (white)

F1 - Vv, Vv, vv, vv

So, the phenotypic ratio is 1 violet : 1 white.

So, the genotypic constitution of the parent having violet-coloured flowers was heterozygous(Vv).

A pea plant parent having violet-coloured flowers with unknown genotype was crossed with a plant having white-coloured flowers. In a progeny, 50% of the flowers were violet and 50% were white. The genotypic constitution of the parent having violet-coloured flowers washeterozygous(Vv).
