  2. Changes within a species which can occur over dozens or hundreds of generations

  3. microevolution

  4. Changes in a population over longer periods of time and include origin of new species.

  5. macroevolution

  6. What is a gene pool?

  7. All the allele for an organism in a population

  8. If you have 48 alleles for one trait and 52 for another. What are the allele frequencies of each?

  9. .48 and .52

  10. The frequency of four alleles add up to ___?

  11. 1

  12. Two or more alleles for a trait in a gene pool are

  13. Polymorphic

  14. The genomes of two individuals (human) is ___ identical?

  15. 99.9%

  16. What are 2 sources for genetic variation?

  17. Mutation and recombination

  18. What is the “unit” of evolution?

  19. population

  20. List 3 things that affect the gene pool.

  21. Mutation, size of population,migration

  22. The HW model is a mathematical relationship of allele___ in a gene pool.

  23. frequencies

  24. P+q = 1, what is p?

  25. Allele frequency

  26. What is the summary of HW to find the % of occurrence of a heterozygous trait.

  27. 2pq

  28. If 49% of a population have the recessive trait, What is the % of the population that are heterozygous?

  29. 42%

  30. What are 5 of the assumptions of HW.

  31. Diploid, nonoverlapping generations, large population, no mutations, sexual reproduction, random mating, no migration

  32. _____ is the most important factor in changes in gene pools

  33. Natural selection

  34. What is an environmental factor of sickle cell disease?

  35. malaria

  36. Evolution promoted by migration between gene pools is called__

  37. Gene flow

  38. A new population can have alleles frequencies that are very different from its source population is called

  39. Founders effect

  40. Small populations have many problems maintaining stable numbers because of___

  41. Inbreeding depression

  42. What does QTL stand for?

  43. Quantitative Trait Loci

  44. Give an example of a quantitative trait

  45. Size (anything that is measured)

  46. Breeding allows for quantitative traits to be used, is called

  47. Artificial selection

  48. Twin studies have shown that for most human behavioral traits___ factors are more important (gene or environmental)

  49. environmental

  50. What information can QTL mapping provide?
