Question

A cross between the two parents results in 50 offspring. How many of the offspring are most likely to have the dominant trait?

Answer 1

The answer will be D. 38

Answer 2

As  you see on the table, there are 3 ways the offspring can get the dominant trait. RR, Rr, and rR (order was switched for clarification). There are 4 total outcomes. In this case, the problem can just be treated as a probability question.

3 out of 4, or 3/4 * 50 is 37.5, which can be rounded to D. 38.
