From a P0 peaplant with purple flowers and a pea plant with white flowers, she got 1 purple F1 hybrid (she had forgotten towater, so just one survived). From this self-fertilized F1 she got 8 F2 offspring. 7 were purple and 1 was white, for a7:1 ratio. Did your little sister just disprove Mendel’s laws?
