Question

If you selected a grey seeded plant in the F2 generation how would you determine if the plant is homozygous or heterozygous?

Answer 1

Depending on the F1 generation (parent) phenotype we can determine whether or not it is homozygous or heterozygous. Also, check to if the F2 grey seeded plant is a mixture of Black and white or if grey is a dominant color. If it is a mixture, it would make it heterozygous. If not and Grey is domminant it would make it homozygous.
