13. A pea plant purebred to produce round yellow peas is crossed with a plant
purebred to produce wrinkled green peas. Round pea shape is dominant to wrinkled,
and yellow pea color is dominant to green. Members of the resulting F1 generation are
then crossed to produce an F2 generation, as shown in the figure. On average, what
fraction of the F2 generation will display both recessive traits?
O A. 0 out of 16 plants will display both recessive traits.
OB. 1 out of 16 plants will display both recessive traits.
C. 6 out of 16 plants will display both recessive traits.
0 D. 4 out of 16 plants will display both recessive traits.
