In mice, the ability to run normally is a dominant trait. Mice with this trait are called running mice (R). The recessive trait causes mice to run in circles only. Mice with this trait are called waltzing mice (r). Hair colour is also inherited in mice. Black hair (B) is dominant over brown hair (b).For each of the following problems, determine the parent genotypes, determine possible gametes by constructing a Punnet square to solve and list the genotypes and phenotypes of the offspring.
a. Cross a heterozygous running, heterozygous black mouse with a homozygous running, homozygous black mouse
b. Cross a waltzing brown mouse with a waltzing brown mouse
