Questions based on paragraph A geneticist made a cross between two pea plants having axillary flowers (AA) and round shaped seeds (RR) with plants having terminal flowers (aa) and wrinkled seeds (rr). In F_1 generation, he obtained plants with axillary flowers and round shaped seeds. But in F_2 generation, he obtained new combinations along with parental combinations. Write the gametes formed by the individual in F_1 generation.
