Across
- 4. middle of the curve has higher fitness
- 6. both ends of the curve have a higher fitness than the middle
- 7. change when only a few move to a new area and become the dominant alleles
- 9. a change following a dramatic reduction in the size of a population
- 10. one end of bell curve has higher fitness
Down
- 1. change can cause alleles to become more or less common
- 2. a group of individuals of the same species that can interbreed
- 3. structures that serve no function anymore
- 5. all the genes and their alleles in a population
