In pepper plants, green (G) fruit color is dominant to red (g) and round (R) fruit shape is dominant to square (r) fruit shape. A) What gamete types will be produced

by a heterozygous green, round plant? B) If two such heterozygous plants are

crossed, what would be the genotypic and phenotypic ratios that would be seen in the offspring? (Punnett Square !)

See How they Run…..

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, possible gametes, then construct a Punnett square to solve.

1. Cross a heterozygous running, heterozygous black mouse with a homozygous running, homozygous black mouseParental genotypes ______________Possible gametes _____ _____ _____ _____Offspring phenotypic ratio ________________
