In mice, agouti fur is a dominant trait resulting in individual hairs having a light band of pigment on an otherwise dark hair shaft. a mouse with agouti fur is shown here, along with a mouse with solid color fur, which is the recessive phenotype (a = agouti; a = solid color).a separate gene, which is not linked to the agouti gene, can result in either a dominant black pigment or a recessive brown pigment (b = black; b = brown).a litter of mice from the mating of two agouti black parents includes offspring with the following fur colors: * solid color, black * solid color, brown (sometimes called chocolate) * agouti black * agouti brown (sometimes called cinnamon) what would be the expected frequency of agouti brown offspring in the litter?
