Across
  1. 2. isolation of a population due to physical barriers such as a fence, mountain range, or body of water
  2. 4. Hardy-weinberg equation that that states that all the homozygous dominant individuals (p2) + all the heterozygous individuals (2pq) + all the homozygous recessive individuals (q2) represent all the individuals in a population
  3. 6. Type of natural selection in which individuals with the average phenotype have an advantage
  4. 11. Measurement of the ability of an individual to survive and reproduce successful offspring
  5. 12. Percent of individuals of a population that have a particular trait - expressed as a number between 0 and 1
  6. 14. When a population experiences a rapid, drastic reduction in the number of individuals in the population
  7. 17. refers to the differences among individuals in a population
  8. 18. Hardy-weinberg equation that states that all the dominant alleles (p) + all the recessive alleles (q) represent all the alleles present in a population
  9. 19. a necessary or desired commodity in an ecosystem - individuals of a population will compete for these
  10. 21. Describes the movement of genes/alleles/individuals between 2 neighboring populations - makes populations more alike
  11. 23. any characteristic that increases the fitness of an individual
  12. 24. the idea that those individuals best suited to their environment will achieve higher fitness
Down
  1. 1. Type of natural selection in which individuals at either extreme of the bell curve achieve higher fitness
  2. 3. Migration of individuals out of a population
  3. 5. Selection within a population due to human interference and selection of desired traits
  4. 7. Migration of new individuals into a population
  5. 8. State of genetic equilibrium characterized by a large population, no migration, no natural selection, no mutations, and random mating
  6. 9. Type of natural selection in which individuals with one extreme phenotype have an advantage
  7. 10. Isolation of a population due to differences in communication, mating rituals, or other behaviors
  8. 11. When a small part of a population is separated from the rest and colonizes a new area
  9. 13. random changes in allele frequencies attributed to luck, not fitness
  10. 15. When organisms will impersonate other organisms to increase fitness
  11. 16. collection of all the alleles present in a population
  12. 20. Isolation of a population due to differences in the timing of mating
  13. 22. Group of individuals of the same species that live in the same area at the same time and can interbreed
