A pea plant that is homozygous dominant for pea shape and heterozygous for pea color is crossed with a pea plant that is homozygous recessive for both pea shape and pea color. What are the possible genotypes of the offspring of this cross? You may find it useful to use a Punnett square to answer this question. Choose 2 answers: A rryy A B RrYY RrYY D Rryy

## Step 1<br />The problem involves understanding the principles of genetics, specifically the concepts of homozygous dominant, heterozygous, and homozygous recessive. The problem also requires the use of a Punnett square to predict the possible genotypes of the offspring.<br /><br />## Step 2<br />The problem states that a pea plant with a homozygous dominant genotype for pea shape (RR) and a heterozygous genotype for pea color (Yy) is crossed with a pea plant that is homozygous recessive for both traits (rryy).<br /><br />## Step 3<br />The Punnett square is a graphical representation used to predict the genotypes of the offspring. In this case, the Punnett square would look like this:<br /><br />\[<br />\begin{array}{c|cc}<br /> & R & r \\<br />\hline<br />Y & RY & ry \\<br />y & Ry & ry \\<br />\end{array}<br />\]<br /><br />## Step 4<br />From the Punnett square, we can see that the possible genotypes of the offspring are RrYy and Rryy. The RrYy genotype corresponds to a pea plant that is heterozygous for both traits, while the Rryy genotype corresponds to a pea plant that is homozygous dominant for pea shape and heterozygous for pea color.
