Question

If the allele B represents black fur and the allele b represents white fur, what would be the phenotype of an animal with the genotype Bb

A. Spotted fur
B.white fur
C. Black fur
D. Grey Fur

Answer 1

Option C, Black fur

Step-by-step explanation:

A dominant allele is one which will overshadow/restrict the expression of trait of recessive allele. Thus, when a dominant allele and recessive allele appears together in the genotype of offspring , only the trait associated with the dominant allele is expressed.

Here in this case B is the dominant allele which is associated with Black color of fur and b is the recessive allele which is associated with white fur. Thus, when B and b appears together, only the trait “ black color of fur” associated with dominant allele B is expressed.

Answer 2

Answer - C. Black Fur

Reason - Since black fur is dominant with upper case B regardless if that other species have a lower case b. The dominant will always be first since b is recessive. But if it's bb it's a different story. For now it's Bb so it's black fur
