Based on this information, what is Fieval's phenotype for the fur color trait?

 - brown fur
 - black fur
You need to determine Fieval's phenotype for the fur color trait. First, consider the alleles in Fieval's genotype for the fur color gene. Then, decide whether these alleles are dominant or recessive.
The allele for brown fur (f) is recessive to the allele for black fur (F). This means F is a dominant allele, and f is a recessive allele.
Fieval's genotype of Ff 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, Fieval's phenotype for the fur color trait must be black fur.
