Question

If a pea plant is Yy, what is its genotype and phenotype (in that order)? (Y is the allele for a yellow pea color and y is for green pea color).

Answer 1

A pea plant with a genotype of Yy is heterozygous with one dominant allele for yellow pea color, and its phenotype is yellow peas since the dominant allele masks the recessive one.

Step-by-step explanation:

If a pea plant is Yy, its genotype is heterozygous, meaning it has one dominant allele (Y) and one recessive allele (y). In this case, Y is the allele for yellow pea color, which is dominant, and y is for green pea color, which is recessive. Since the dominant allele masks the effect of the recessive allele in a heterozygote, the phenotype of this pea plant would be yellow peas.
