A pea plant is heterozygous for both seed shape and seed color. S is the allele for the dominant, spherical shape characteristic; s is the allele for the recessive, dented shape characteristic. Y is the allele for the dominant, yellow color characteristic; y is the allele for the recessive, green color characteristic. A pure bred plant with green spherical shaped seeds is crossed with a pure bred plant with yellow dented shaped seeds. State the phenotype and genotype for the parent plants p1 and p2

Answer:

The correct answer is -

P1: SSyy

p2: ssYY

Step-by-step explanation:

In the given question it is given that S is the allele for the dominant trait of spherical shape over s allele of dented shape and similarly Yellow pea seed is dominant over y green seed.

It is given that parent 1 or p1 is true breeding for green spherical shaped seeds which means it has two alleles of the same gene that are SSyy (S for spherical and y for green) and parent 2 or p2 is a pure bred plant with yellow dented shaped seeds that would be ssYY.
