A snapdragon plant that bred true for white petals was crossed to a plant that bred true for purple petals, and all the F1 had white petals. The F1 was selfed. Among the F2, three phenotypes were observed in the following numbers

white                              240

solid-purple                    61

spotted-purple                19

Total                              320

Which of the following reason to deviation f2 phenotype ratio ?
