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