Based on this information, what is Squeaky's phenotype for the albinism trait?

 - having albinism
 - not having albinism
You need to determine Squeaky's phenotype for the albinism trait. First, consider the alleles in Squeaky's genotype for the albinism gene. Then, decide whether these alleles are dominant or recessive.
The allele for having albinism (a) is recessive to the allele for not having albinism (A). This means A is a dominant allele, and a is a recessive allele.
Squeaky'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, Squeaky's phenotype for the albinism trait must be not having albinism.
