1 Pigeons may exhibit a checkered or plain color pattern. In a series of controlled matings, the following data were obtained. P1 Cross F1 Progeny Checkered Plain (a) checkered * checkered 36 0 (b) checkered * plain 38 0 (c) plain * plain 0 35 Then F1 offspring were selectively mated with the following results. (The P1 cross giving rise to each F1 pigeon is indicated in parentheses.) F1 : F1 Crosses F2 Progeny Checkered Plain (d) checkered (a) * plain (c) 34 0 (e) checkered (b) * plain (c) 17 14 (f) checkered (b) * checkered (b) 28 9 (g) checkered (a) * checkered (b) 39 0 How are the checkered and plain patterns inherited? Select and assign symbols for the genes involved, and determine the genotypes of the parents and offspring in each cross.
