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