chapters 16/17 Jason Head
Across
- 5. no longer interbreed
- 7. is all the genes, and their alleles, in the
- 8. both ends of the curve have a higher fitness than the middle
- 9. is formation of a new species.
- 10. a change when only a few move to new area and become the dominant alleles for that population.
Down
- 1. middle of the curve has higher
- 2. is controlled by 2 or more genes.
- 3. a change following a dramatic reduction in the size of the population.
- 4. one end of bell-curve has higher
- 6. is the number of times that the allele occurs in a gene pool.
