Respuesta :
yeah, i'm pretty sure it's d. phenotype meaning physical which include none of the above. correct me if i'm wrong, that's my guess.
Answer:
The correct answer would be A. brown.
It can be explained with the help of the law of dominance which states that the dominant allele expresses itself and masks the expression of a recessive allele in a heterozygous condition.
Thus, in genotype Bb, B being a dominant allele would express itself and mask the expression of a recessive allele that is, b.
Hence, the phenotype of a guinea pig with Bb genotype would be a brown fur.
