Across
- 5. a trait controlled by only one gene
- 6. the number of times that the allele occurs in a gene pool, compared with the number of times other alleles for the same gene occur
- 7. a change following a dramatic reduction in the size of the population
- 9. one end of the bell curve has higher fitness
- 10. is all the genes, and their alleles, in the population
Down
- 1. both ends of the curve have a higher fitness than the middle
- 2. a change when only a few move a new area and become the dominant alleles for that population
- 3. middle of the curve has higher fitness
- 4. a group of individuals of the same species that can be interbred
- 8. a trait controlled by two or more genes
