Across
- 3. both ends of the curve have a higher fitness than the middle
- 6. is a trait controlled by only one gene
- 7. any changes in a sequence of DNA
- 8. is all the genes, and their alleles, the population
- 9. a change following a dramatic reduction in the size of the population
- 10. occurs during gamete formation
Down
- 1. one end of bell-curve has higher fitness
- 2. middle of the curve has higher fitness
- 4. is controlled by 2 or more genes
- 5. a change when only a few move to new area and become the dominant alleles for that population
