In a certain type of flower red petals (R) are dominant to white petals (r). If a flower has the genotype Rr, which of the following phenotypes would it have?
Answer explanation
In simple Mendelian inheritance, the presence of even one dominant allele means that the dominant phenotype will be shown. Even though the genotype is heterozygous (Rr), the recessive allele will be covered up by the dominant allele and the flower will be red.
