Question

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**

Answer 1

The phenotype of a pea plant with genotype Rr would be round peas.

Here is a Punnett square to illustrate this:

R r
R RR Rr
r Rr rr

In this square, the possible combinations of alleles are RR, Rr, Rr, and rr. Since the allele for round peas (R) is dominant over the allele for wrinkled peas (r), any individual with at least one R allele will have round peas. Therefore, individuals with genotypes RR and Rr will both have the phenotype of round peas.
