In a summer squash, white fruit color (W) is dominant over yellow fruit (w) and disk-shaped fruit (D) is dominant over sphere-shaped fruit (d). If a squash plant true-breeding for white, disk-shaped fruit is crossed with a plant true-breeding for yellow, sphere-shaped fruit, what are the possible genotypes and phenotypes of their offspring.

3. 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 color 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 then construct a Punnett Square to solve.
a. Cross a heterozygous running, heterozygous black mouse with a homozygous running, homozygous black mouse
b. Cross a homozygous running, homozygous black mouse with a heterozygous running brown mouse.
