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

Explanation:

Mendel's experiment: Purebred purple (PP) and purebred white (pp) plants are crossed. The purple allele (P) is dominant, white (p) recessive. Each parent contributes one allele: PP gives P, pp gives p. Offspring genotypes are all Pp. Since P is dominant, all (100%) show purple phenotype.

Answer:

100 percent purple
