In pea plants, the allele for round peas, R, is dominate over the allele for wrinkled peas, r, what is the phenotype of a pea plant with phenotype Rr?

The phenotype of a pea plant with the genotype Rr would be the round pea phenotype. The dominant allele R would determine the physical characteristics of round peas, while the recessive allele r would not have an observable effect on the phenotype.
