If a round, green seeded pea plant (RR yy) is crossed with wrinkled, yellow-seeded pea plant, (rr YY) the seeds produced in F1 generation are
(a) round and yellow
(b) round and green
(c) wrinkled and green
(d) wrinkled and yellow
The cross between RRyy and rrYY seeds will produce RrYy (round and yellow) seeds in the F1 generation because round and yellow are dominant traits.
Therefore, option (a) is correct.
