Question

A female mouse has white fur; a male mouse has brown fur. The two mice have a litter of seven pups, five of the pups have brown fur, two pups had white fur. What can this example tell us about genetics? Use the terms inherit, gene, allele, dominant, recessive, purebred, and hybrid in your explanation.

Answer 1

Step-by-step explanation:

A female mouse has white fur; a male mouse has brown fur. The two mice have a litter of seven pups, five of the pups have brown fur, two pups had white fur.

The female mouse fur which is white is inherited in the recessive condition i e it is recessive to the brown fur which is that of the male and the female is purebred meaning she has this gene in the homozygous form. The male that has brown fur seeing that the mating produces both brown and white, the male has inherited this gene as a hybrid (combination of the two alleles: one allele for brown and one for white). This has given us a little idea of what genetics is all about.
