The allele for brown fur in mice (B) is dominant over the allele for white fur (b).
evablogger [386]

Answer:

Genotype: Bb (heterozygous)

Phenotype: brown fur

Explanation:

Since allele B is dominant to allele b, as long as genotype has allele B in it, its effect of phenotype will be expressed instead, regardless of whether allele b is present.

As mouse genotype is stated as Bb, on the chromosome from its parents, allele B comes from one parent while allele b is inherited from the other parent.

Phenotype is the expressed trait. In this case, as genotype has allele B, the phenotype will be brown fur as its effect is expressed.
