In pea plants, the allele for round peas, R, is dominant over the allele for wrinkled peas, r. What is the phenotype of a pea plant with genotype Rr? **Make a punnet square for help** (1 point)

Answer 1

To create a Punnett square for this problem, we will list the possible genotypes of the offspring resulting from the cross between two parents with the genotype Rr.

Parent 1: Rr
Parent 2: Rr

The Punnett Square would look like this:

R r
R | RR | Rr |
r | Rr | rr |

In this case, there are 4 possible genotypes: RR, Rr, Rr, and rr.

When it comes to the phenotype, since the allele for round peas (R) is dominant over the allele for wrinkled peas (r), the presence of at least one R allele would result in the round peas phenotype.

Therefore, the phenotype of a pea plant with genotype Rr would be round peas.
