A species of horse have a coat that appear red or white in color.

A solid red coat horse has a genotype of C^RC^R while a solid white coat horse has a genotype of C^WC^W. A heterozygous horse appears to have both a red and white coat, called "roan".

When a red-coated horse mates with a heterozygous (roan) horse, what is the expected ratio of the resulting offspring?

An eggplant farmer has purple, white, and violet-colored eggplants for sale. The farmer knows that the allele for purple eggplants (E^P) is incompletely dominant over the allele for white eggplants (E^W). This means that violet eggplants are heterozygotes.

Determine which of the following Punnett squares shows a cross between a violet eggplant and a white eggplant.

A model of the coat color in mice is shown below.

Which Punnett square represents a cross that would produce a brown mice offspring?
