Question

in rabbits, b represents the allele for black coat and b represents the allele for white coat. black is dominant over white. if a rabbit has the genotype bb, what is the rabbits phenotype? a gray b black c white d bb × bb

Explanation:

In genetics, the phenotype is the observable physical trait. When an allele is dominant (B for black coat), it will show its trait even if there is a recessive allele (b for white coat) present. Since B (black) is dominant over b (white), a rabbit with genotype Bb will have the black coat phenotype.

Answer:

B. black
