Based on this information, what is Clyde's phenotype for the coat pattern trait?

 - white spots
 - solid coloring
You need to determine Clyde's phenotype for the coat pattern trait. First, consider the alleles in Clyde's genotype for the coat pattern gene. Then, decide whether these alleles are dominant or recessive.
The allele for solid coloring (A) is dominant over the allele for white spots (a). This means A is a dominant allele, and a is a recessive allele.
Clyde's genotype of Aa has one dominant allele and one recessive allele. An organism with at least one dominant allele for a gene will have the dominant allele's version of the trait. So, Clyde's phenotype for the coat pattern trait must be solid coloring.
