5. Pigeons exhibit a checkered or plain feather pattern. In a series of controlled matings, the following data were obtained: F, Progeny P, Cross Checkered Plain 36 (a) checkered X checkered (b) checkered X plain (c) plain 38 X plain 35 Then F, offspring were selectively mated with the following results. (The P, cross giving rise to each Fi pigeon is indicated in parentheses.) See Now Solve This on page 41.
