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?(1 point)
The phenotype of a pea plant with genotype Rr is the round pea phenotype.
The phenotype of a pea plant with genotype Rr would be round peas, as the allele for round peas is dominant over the allele for wrinkled peas.
To determine the phenotype of a pea plant with the genotype Rr, you need to understand the concept of dominance and recessiveness in genetics. In this case, the allele for round peas (R) is dominant over the allele for wrinkled peas (r).
When an organism has a dominant allele (uppercase letter) along with a recessive allele (lowercase letter) for a particular trait, the dominant allele determines the physical appearance or phenotype of the organism.
In the case of Rr genotype, the dominant allele R will be expressed, resulting in the phenotype with round peas. Thus, the phenotype of a pea plant with the genotype Rr is round peas.
To summarize:
Genotype: Rr
Phenotype: Round peas
