Genotype and Phenotype: Understanding Genetic Traits in Rabbits

What are the genotype and phenotype of a rabbit that is heterozygous for fur color, where black fur is dominant (B) and brown fur is recessive (b)? The rabbit's genotype and phenotype would be Bb and black fur type respectively.

Genotype and Phenotype

Genotype refers to the genetic components of a trait while phenotype refers to the physical expression of a trait.

Since the rabbit is heterozygous, it means that the genotype consists of 2 different alleles, unlike homzygous genotypes that consist of the same alleles.

Thus, the genotype of the rabbit would be Bb.

Also, since B (black fur) is dominant over b (brown fur), the phenotype of Bb would be black fur.

Understanding genotype and phenotype is crucial in genetics as it helps predict and explain the physical characteristics of an organism based on its genetic makeup.
