Question

When Mendel crossed purebred purple flowering plants (PP) with purebred white flowering plants (pp), what were the flower colors of the resulting offspring?
25 percent white and 75 percent purple
50 percent white and 50 percent purple
100 percent purple
100 percent white

Answer 1

100 percent purple

Explanation: Purple (P) is dominant over white (p). Crossing PP × pp yields all Pp heterozygotes, which show the dominant purple phenotype.
