The phenotype of a pea plant with genotype Rr is round.
Punnet square:
R r
R | RR Rr
r | Rr rr
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
some round and some wrinkled
slightly wrinkled
round
wrinkled

this is not an optional answer
Apologies for the confusion. The correct phenotypic outcome for a pea plant with genotype Rr is round peas. The round allele (R) is dominant over the wrinkled allele (r), so even if the plant carries one round allele and one wrinkled allele, the round phenotype will be expressed.
