If you are testing traits for mendelian inheritance, how do you calculate the expected values?

n a cross between two heterozygous individuals, the offspring would be expected to show a 3 : 1 ratio. For example, in Case 1, three-fourths of the individuals would have red (wild-type) eyes, and one-fourth would have sepia eyes.

If there are 44 offspring, how many are expected to have red eyes?

We expect three-fourths to have red eyes.
34 of 44 = 33

If there are 44 offspring, how many are expected to have sepia eyes?
14 of 44 = 11

Now you are ready to calculate chi-square.
