A snapdragon plant that bred true for white petals was crossed to a plant that bred for purple petals, and all the F1 had white petals. The F1 was selfed. Among the F2, three other phenotypes were observed in the following numbers. white - 240 solid purple - 61 spotted purple - 19 total = 320 a.) Propose an explanation for these results, showing the genotypes of all generations( F1, F2, F3). Be sure to define your symbols. b.)
