While doing fieldwork in Madagascar, 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 dа ta:

Cross Phenotypes

1 72 red-winged, 24 clear-winged

2 96 red-winged

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