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