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

All the flowers will be purple i.e.,100 percent purple. The reason is in this cross between pure-bred purple flowering plants (PP) with pure-bred white flowering plants (pp), the purple flowering plant(PP) is dominant over white flowering plant(pp) so in F1 generation (between pure-bred dominant and pure-bred recessive) only dominant character will appear in the progeny.
