Question
Chapter 19.4, Problem 3CC
Summary Introduction
To analyze:
If malaria was eradicated, then the frequencies of the HAand Hs alleles over the long run.
Introduction:
Natural selection is the process where an organism with favorable traits is more likely to reproduce, so that they can pass to the pass to the next generation. There are mainly three different types of natural selection.
- Directional
- Stabilizing
- Disruptive
