Across
  1. 2. Isolation due to physical barriers such as mountains or water
  2. 4. Hardy-Weinberg equation stating all genotypes in a population
  3. 6. Average phenotype is favored and extremes are selected against
  4. 11. Measurement of the ability of an individual to survive and reproduce
  5. 12. Percent of individuals with a particular trait expressed between 0 and 1
  6. 14. Rapid drastic reduction in population size
  7. 17. Differences among individuals in a population
  8. 18. Hardy-Weinberg equation stating all dominant and recessive alleles in a population
  9. 19. A necessary or desired commodity in an ecosystem
  10. 21. Movement of genes/alleles/individuals between neighboring populations
  11. 23. Any characteristic that increases the fitness of an individual
  12. 24. Individuals best suited to their environment have higher fitness
Down
  1. 1. Both extremes of a trait are favored over the average
  2. 3. Migration of individuals out of a population
  3. 5. Selection within a population due to human interference
  4. 7. Migration of individuals into a population
  5. 8. State of genetic equilibrium with no evolution occurring
  6. 9. One extreme phenotype is favored over the other
  7. 10. Isolation due to differences in communication or mating rituals
  8. 11. Small group colonizes a new area and evolves differently
  9. 13. Random changes in allele frequencies due to chance
  10. 15. Organisms imitate other organisms to increase fitness
  11. 16. Collection of all the alleles present in a population
  12. 20. Isolation due to differences in timing of mating
  13. 22. Group of individuals of the same species living in the same area and interbreeding
