To make a Punnett square, we will cross a pea plant with genotype Rr (round peas) with a pea plant with genotype rr (wrinkled peas).
| R | r |
--------------
R | RR | Rr |
--------------
r | Rr | rr |
The Punnett square shows that there are two possible genotypes in the offspring: 50% RR (round peas) and 50% Rr (round peas).
Since the allele for round peas (R) is dominant over the allele for wrinkled peas (r), the phenotype of a pea plant with genotype Rr is round peas.
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 punnett square for help**
