The Phenotypes of Rabbits with Genotypes Bb and bb

What are the phenotypes of rabbits with the genotypes Bb and bb?

A. Black coat and black coat

B. Black coat and brown coat

C. Brown coat and black coat

D. Brown coat and brown coat

Final answer: The phenotypes of rabbits with genotypes Bb and bb would be black coat and brown coat respectively. This is because black is dominant over brown in the given context.

Answer

The phenotypes of rabbits with genotypes Bb and bb are black coat and brown coat respectively.

Genotypes and phenotypes are terminologies often used in genetics to describe the genetic makeup and the physical characteristics of an organism. In the case of rabbits with the genotypes Bb and bb, we can determine their phenotypes based on the dominant and recessive traits of the alleles.

The genotype Bb consists of one dominant allele (B) for black coat color and one recessive allele (b) for brown coat color. In this scenario, the dominant allele will determine the phenotype, resulting in a black coat. This is because the black coat color is dominant over the brown coat color.

On the other hand, the genotype bb has two recessive alleles (b) for brown coat color. Since there are no dominant alleles present in this genotype, the phenotype will manifest as a brown coat.

This inheritance pattern follows Mendel's rules of heredity, where dominant traits mask the expression of recessive traits in heterozygous organisms. Understanding genotypes and phenotypes is crucial in predicting and explaining the genetic traits of offspring in breeding programs and genetic studies.
