In some species of jellyfish, red pigment is dominant to orange pigment. Give the genotype and phenotype between a homozygous dominant jellyfish and one that is orange.

If you are asking for the genotypes and phenotypes of the offspring of the jellyfishes the answers are

genotype: Rr (heterozygous dominant)

phenotype: red

Explanation:

A homozygous dominant jellyfish is represented by RR. An orange jellyfish is represented by rr.
