Question

in a group of rabbits, some individuals have black fur and others have brown fur. in this group, the gene for the fur color trait has two alleles. the allele for brown fur (f) is recessive to the allele for black fur (f).
marzipan is a rabbit from this group. marzipan has the homozygous genotype ff for the fur color gene.
based on this information, what is marzipans phenotype for the fur color trait?
brown fur black fur

Explanation:

Recessive alleles only express their phenotype when an organism has two copies (homozygous) of the recessive allele. Here, the brown fur allele ($f$) is recessive, and Marzipan has the homozygous genotype $ff$.

Answer:

brown fur
