Question

What proportion of drake's tested seeds actually sprouted?

Answer 1

In Mendel's experiment, 75% of the F2 offspring were expected to have round seeds. Similarly, in Drake's experiment, 75% of the tested seeds would be expected to sprout.

Step-by-step explanation:

In Mendel's experiment, when true-breeding plants with round seeds were crossed with true-breeding plants with wrinkled seeds, all the F1 offspring had round seeds. When the F1 plants were self-crossed, 75 percent of the F2 offspring were expected to have round seeds, while 25 percent were expected to have wrinkled seeds

. Therefore, in this experiment, 75 percent of Drake's tested seeds would be expected to sprout.
