Question

In a group of cows, some individuals have solid coloring and others have white spots. In this group, the gene for the coat pattern trait has two alleles. The allele A is for solid coloring, and the allele a is for white spots.
Flash, a cow from this group, has white spots. Flash has two alleles for white spots.
Based on this information, what is Flash's phenotype for the coat pattern trait?

Answer 1

Flash's phenotype for the coat pattern trait is "white spots." Since the cow has two alleles for white spots (aa), it expresses the recessive phenotype associated with that genotype. Therefore, Flash is phenotypically identified as having white spots.
