In Drosophila melanogaster, the genes for purple eyes (pr) and curved wings (c) are on the same chromosome. The recombination frequency between pr and c is roughly 20%. Both the purple eyed and curly winged phenotypes are recessive to the wild-type (+) phenotypes (red-eyed and straight winged, respectively).
Consider a cross between a female with genotype (+ c)/(pr +) and a male (pr c)/(pr c). Based on the information above, predict the percentage of offspring of each phenotype from this cross assuming a large number of offspring.
-Wild type (red eyes and straight wings)
-Purple eyes and Straight wings
-Red eyes and Curved wings
