Gregor Mendel was one of the earliest people to study the process of inheritance. In his experiments true-breeding plants with spherical seeds (RR) were crossed with true-breeding plants with dented seeds(rr). Mendel collected the seeds from this cross, grew Fl-generation plants, let them self-pollinate to form a second generation, and analyzed the seeds of the resulting F2 generation. Which statement below best describes the results?

A. 1/2 of the F1 and 3/4 of the F2 generation seeds were spherical.

B. 1/2 of the F1 and 1/4 of the F2 generation seeds were dented.

C. All of the F1 and 3/4 of the F2 generation seeds were spherical.

D. 1/4 of the F1 and all of the F2 generation seeds were spherical.
