While doing field work you discover a new dragonfly species that has either red (R) or clear (r) wings. Initial crosses indicate that R is dominant to r. You perform three crosses using three different sets of red-winged parents with unknown genotype and observe the following data:

Cross

Phenotypes

1

72 red-winged, 24 clear-winged

2

4 red-winged

3

96 red-winged

a. What is the most likely genotype for each pair of parents?

b. Do you think there are a sufficient number of progeny to support each of your answers in the previous question?
