- There is a species of fish in which homozygous recessive (rr) individuals are Yellow and homozygous dominant (RR) individuals are Red. Color in this species of fish exhibits incomplete dominance. If we mate a homozygous dominant individual with a heterozygous individual, what is the phenotypic ratio of the offspring? Group of answer choices 2 Red : 2 Orange. 4 Red. 3 Red : 1 Yellow. 1 Red : 2 Orange : 1 Yellow.arrow_forwardIn a certain breed of dog, the dominant, B, is required for black fur; it’s recessive, b, produces brown fur. However, the dominant, I is the epistatic to the color locus and can inhibit pigment formation. The recessive allele, i, on the other hand, permits pigment deposition in the fur. What would be the phenotypes of the following sets of parents and what would be the results of the mating BBii x bbIi 1/4 black, 1/4 brown, 1/2 no color 1/2 black, 1/2 brown 1/2 black, 1/2 no color 1/3 black, 1/3 no color, 1/3 brownarrow_forwardAccording to the Hardy Weinburg equation, which variable would represent the heterozygous individual?
