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