Question

In a group of rock pocket mice, some individuals have dark fur and others have light fur. In this group, the gene for the fur color trait has two alleles. The allele F is for dark fur, and the allele f is for light fur.
Basil is a rock pocket mouse from this group. Basil's phenotype for the fur color trait is dark fur. Basil's genotype for the fur color gene is Ff.
Based on this information, complete the following statement.

Answer 1

Basil's phenotype for fur color is dark fur because he possesses at least one dominant allele (F) for the trait, and his genotype is heterozygous (Ff), which means he has one dominant allele (F) and one recessive allele (f).
