Question

In pea plants, plant height, seed shape, and seed color are governed by three independently assorting genes. The three genes have dominant and recessive alleles, with tall (T) dominant to short (t), round (R) dominant to wrinkled (r), and yellow (G) dominant to green (g).

Part D

What proportion of the F2 are expected to be TtRRgg? (Hint: Consider the probability of obtaining each genotype for the three genes separately and then use the product law.)

Express your answer using three decimal places.
