Question

A violet.pea plant VV was crossed with a white plant vv. F1 generation was allowed to self pollinate and F2 generation was also obtained.
i).What would be the phenotype of plants in F1 generation​

Answer 1

The genotypic ratio will be

1(VV) : 2(Vv) : 1(vv)

VV = homozygous tall

Vv = heterozygous tall

vv = homozygous dwarf

The phenotypic ratio will be

3(Tall) : 1(Dwarf)

A) The phenotype of all plants in F1 generation will be Vv ( heterozygous tall).

B) Percentage of plants having white flowers is 25%.

C) The ratio of vv:Vv = 1:2
