In a group of Syrian hamsters, some individuals have straight fur and others have wavy fur. In this group, the gene for the fur texture trait has two alleles. The allele for wavy fur (f) is recessive to the allele for straight fur (F).

Briar is a Syrian hamster from this group. Briar has the homozygous genotype ff for the fur texture gene.

In the Syrian hamster fur texture trait where wavy fur (f) is recessive to straight fur (F), what is...

Answer

Briar’s phenotype is wavy fur. Because Briar is homozygous recessive ($ff$), the recessive wavy-fur trait is expressed.

Explanation

What the genetics statement is telling you

You are told there are two alleles for fur texture, with straight fur ($F$) dominant and wavy fur ($f$) recessive. Your job is to translate Briar’s genotype into the visible trait (phenotype).

Dominant vs. recessive: when does each show?

A dominant allele shows if there is at least one copy: $F\_$ gives straight fur.
A recessive allele shows only if both copies are recessive: $ff$ gives wavy fur.

Applying it to Briar’s genotype $ff$

Briar has two recessive alleles ($ff$). That means there is no dominant $F$ allele to mask the recessive trait, so Briar will have wavy fur.
