-The expected phenotypic ratio of offspring.
-The expected genotypic ratio of offspring.
-Calculate the expected values you would use on a chi-square test (use genotypic ratio if available)
-Find the degrees of freedome
-Perform a chi-square test

a. A cross was performed between two black mice who are known to be heterozygous for that coat color trait. They produce 23 offspring in the first generation. Seventeen black and six white.

b. A cross was performed between two pink snapdragons( recall from Bio 1 snapdragons are an example of incomplete dominance). There are 200 offspring on the F1: 98 pink 49 red and 53 white.
