Pea plants make excellent models for genetic crosses, as they display a number of characteristics that demonstrate a complete dominance inheritance pattern, such as flower color, seed shape, seed color, and plant height. A certain variety of pea plants produces green (G) and yellow (g) peas. A pea plant with green peas is crossed with a pea plant with yellow peas. Select the possible genotype(s) of the green parental plant.

AZ · Answer

We're looking for the possible genotype of the Green parental plant

Remember that Green (G) is dominant so if you have at least one allele of that, then the peas will be green

For the peas to be yellow, you would need to have both alleles for yellow peas since yellow is recessive.

So what are the two possible genotypes of the Green parental plant?
