In a plant, a single locus affects both berry color and berry size.There are two mutant alleles (R₁ and R₂) in addition to the wild-type allele (R₀).Individuals that are R₀R₀ have large, white berries.Individuals that are R₁R₁ or R₀R₁ have red berries, individuals that are R₂R₂ or R₀R₂ have small berries, and R₁R₂ individuals have berries that are both red and small.Thus, A) R₁ is dominant to R₂. B) R₂ is dominant to R₁. C) R₁ and R₂ exhibit incomplete dominance. D) R₁ and R₂ exhibit pleiotropy. E) R₁ and R₂ exhibit codominance.

The Answer of In a plant, a single locus affects both berry color and berry size.There are two mutant alleles (R₁ and R₂) in addition to the wild-type allele (R₀).Individuals that are R₀R₀ have large, white berries.Individuals that are R₁R₁ or R₀R₁ have red berries, individuals that are R₂R₂ or R₀R₂ have small berries, and R₁R₂ individuals have berries that are both red and small.Thus, A) R₁ is dominant to R₂. B) R₂ is dominant to R₁. C) R₁ and R₂ exhibit incomplete dominance. D) R₁ and R₂ exhibit pleiotropy. E) R₁ and R₂ exhibit codominance.
