Understanding Mendelian Genetics: The Case of Fur Color in Rabbits

What are the dominant and recessive fur colors in rabbits according to Mendelian Genetics?

Answer:

In rabbits, black fur (B) is considered dominant over white fur (b) according to Mendelian Genetics.

The Role of Dominant and Recessive Genes

Mendelian Genetics, named after the Austrian monk Gregor Mendel, lays the foundation for understanding inheritance in living organisms. In the case of fur color in rabbits, the color is determined by the presence of certain genes.

When it comes to fur color in rabbits, black fur (B) is considered dominant, while white fur (b) is recessive. This means that if a rabbit carries one gene for black fur (B) and one gene for white fur (b), the black fur trait will be expressed.

On the other hand, if a rabbit carries two genes for white fur (bb), the white fur trait will be expressed. This is due to the fact that the presence of the dominant gene (B) suppresses the expression of the recessive gene (b) in the case of rabbits' fur color.

Therefore, when a purebred black furred male (BB) is bred with a female that has the recessive white fur (bb), the offspring will inherit one dominant gene for black fur and one recessive gene for white fur (Bb). This results in offspring that exhibit black fur, continuing the dominant trait of black fur in the genetic lineage.
