Two pea plants – one with round yellow seeds (RRYY) and another with wrinkled green (rryy) seeds produce F1 progeny that have round, yellow (RrYy) seeds. When F1 plants are self-pollinated, which new combination of characters is expected in F2 progeny? How many seeds with these new combinations of characters will be produced when a total 160 seeds are produced in F2 generation? Explain with reason.

Cross-pollination is a plant reproduction process where pollen is transferred from the male reproductive organ of one flower to the female reproductive organ of another, enhancing genetic diversity.
