Question

You have a pea plant with a yellow pea phenotype but do not know if the genotype is homozygous (YY) or heterozygous (Yy). What type of cross would you do determine the genotype of this plant and what would be the predicted phenotypes of the offspring?

Answer 1

Answer: given -->  a pea plant with a yellow pea phenotype.

Explanation:

if its is round in shape then its a homozygous but if it is wrinkled in shape then its type is heterozygous.

To determine the genotype of this plant, we can use double gene cross method taking two possibilities - round and yellow or wrinkled and yellow.

its predicted phenotype can be 1:3:3:1.
