I’m peas plants, the allele for round peas, R, dominant over the allele for wrinkled peas, r. What is the phenotype of a plant with genotype art?

The genotype "art" does not represent a valid genotype for pea plants. The correct symbols for the alleles in question are "R" for round peas and "r" for wrinkled peas. Therefore, the given genotype does not provide enough information to determine the phenotype of the plant.
