You are asked to find the genotype of a pea plant bearing violet flowers, growing in your school garden. Give your explanation to get the solution.
Carry a test cross and then cross the violet flower-bearing plant with the white flower-bearing plant after that cross the violet flower-bearing plant with the homozygous recessive plant. Now if the progeny has 100% violet flowers, then the unknown genotype is homozygous dominant but if the progeny has 50% violet flower and 50% white flower, then the unknown genotype is heterozygous dominant.
