died from sickle cell disease before reproducing.

Answer 1

The correct answer is:

**had the same likelihood to survive and reproduce as his peers.**

In a region without malaria, the presence of the sickle cell mutation would not provide a selective advantage, and thus, a carrier of the mutation would likely have a similar likelihood of survival and reproduction compared to their peers without the mutation.
