Across
- 6. middle of the curve has higher fitness
- 7. selection- both ends of the curve have a higher fitness than the middle
- 8. is 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
- 9. is a group of individuals of the same species that can interbreed
- 10. a change following a dramatic reduction in the size of the population
Down
- 1. is controlled by 2 or more genes
- 2. one end of bell-curve has higher fitness
- 3. is all the genes, and their alleles, in the population
- 4. In small populations, chance can cause alleles to become more or less common which is called
- 5. is a trait controlled by only one gene
