Across
  1. 8. organisms that are more adapted to their environment are more likely to survive and pass on the genes that aided their success
  2. 10. random changes that can potentially lead to new adaptations that increase the fitness of an individual
  3. 11. individuals with one extreme version of a trait have higher fitnessStabilizing
Down
  1. 1. a change in the allele frequency of a population as a result of chance events rather than natural selection
  2. 2. a type of genetic that has been around for years
  3. 3. the amount of reproduction of an individual compared with the reproductive output
  4. 4. the permanent movement of genes into or out of a population resulting in a change in allele frequenciesStabilizing individuals with an intermediate version of a trait are the most fit
  5. 5. individuals with extreme versions of a trait have higher fitness than those with intermediate versionsMutations
  6. 6. the relative frequency of an allele at a particular locus in a population
  7. 7. a feather peacock is attracted to a male with the most beautiful tail feathers
  8. 9. is evolution a random process?
