Across
  1. 3. type of natural selection in which individuals with the average phenotype have an advantage and the extremes are selected against
  2. 7. state of genetic equilibrium characteristics by a large population, no migration, no natural selection, no mutations, and random mutation
  3. 11. isolation of a population due to differences in the timing of mating
  4. 13. selection within a population due to human interference and selection of desired traits
  5. 14. describes the movement of genes/alleles/individuals between 2 neighboring populations-makes populations more alike
  6. 16. type of natural selection in which individuals with one extreme phenotype have an advantage and the other extreme is selected against
  7. 18. migration of new individuals into a population
  8. 19. when a small part of a population is separated from the rest and colonizes a new area- they often respond differently to natural selection pressures
Down
  1. 1. isolation of a population due to physical barriers such as a fence, mountain range, or body of water
  2. 2. type of natural selection in which individuals at either extreme of the bell curve achieve higher fitness and the average is selected against
  3. 4. when organisms will impersonate other organisms to increase fitness
  4. 5. hardy-weinberg equation that states that all the dominant alles(p)+all the recessive alleles(q) represent all the alleles present in a population
  5. 6. the idea that the individuals best suited to their environment will achieve higher fitness
  6. 8. isolation of a population due to differences in communication, mating rituals ,or other behaviors
  7. 9. any characteristic that increases the fitness of an individual
  8. 10. percent of individual of a population that have a particular trait-expressed as a number between 0 and 1
  9. 12. collection of all the alleles present in a population
  10. 14. random changes in allele frequencies attributed to luck, not fitness
  11. 15. group of individuals of the same species that live in the same area at the same time and can interbreed
  12. 17. measurement of the ability of an individual to survive and reproduce successful offspring
