Question 15 of 40

2.5 Points
For her science fair project, your little sister replicated one of Mendel’s experiments. From a P0
pea plant with purple flowers and a pea plant with white flowers, she got 1 purple F1 hybrid (she
had forgotten to water, so just one survived). From this self-fertilized F1 she got 8 F2 offspring.
7 were purple and 1 was white, for a 7:1 ratio.
Did your little sister just disprove Mendel’s laws?
Feedback: Learning Objective: Analyze Mendelian and Non-Mendelian inheritance patterns
