  1. what is a fixed and lost allele
  2. Population genetics
  3. genetic marker
  4. balancing selection
  5. hypothesis
  1. a the study of allele frequencies of populations and how they change over time. It is based on mendelian genetics.
  2. b within a population a fixed allele is one that is adopted by every member and the lost allele is the allele that was in competition that none of the organisms have it is common in directional selection but not always evident
  3. c a specific allele that causes a distinctive phenotype
  4. d no particular allele has a distinct advantage instead there is a balace of several alleles in terms of their fitness and frequency. this usually happens because an enviroment varies over time meaning there is a heterozygous advantage, it also happens because some alleles are rare and favored over common ones like guppies who mate with rare patterned individuals because common patterns get recognized and eaten first.
  5. e testable statement of relationships which can be confirmed or falsified a hypothesis driven inquiry is self correcting

5 Multiple choice questions

  1. • To aid our memory and help organize them,
    • Aid in prediction of relationships,
    • Provide unique universally used names like the Latin terms.
  2. depicts the pattern evident in the history of decent groups of organisms it's more of a hypothesis.
  3. a genetic constraint that prevents an organism from making a change that would improve its fitness because it lacks the prerequisite genes.
  4. larger evolutionary change ( often in morphology) warranting placement of populations in diff genera or high level taxa.
  5. a change in allele frequencies occurring due to genetic drift when a new population is established from a small sample of the original population called a founder event

5 True/False questions

  1. does natural selection change individualsan average difference between the survival/ reproduction of individuals with certain phenotypes relative to individuals with other phenotypes. only mechanism that can produce adaptation


  2. Darwingeneralizations that describe phenomena


  3. what are the three domainsarchaea bacteria and eukarya


  4. what indicated the earth was much older than 6000 years?bacteria, archaea, protists, plantae, fungi and animalia


  5. do organisms act for the good of the speciesauthority, belief, logic and science
