5 Written questions

5 Matching questions

  1. genes are carried on
  2. allopatric speciation
  3. gradualism
  4. homologous traits
  5. phylogeny
  1. a chromosomes
  2. b speciation that occurs when two or more populations of a single species are geographically isolated from each other and then diverge to form two or more new species
  3. c the evolutionary relationships among a group of species. diagrammed as a family tree
  4. d opposite of punctuated equilibrium
  5. e structural similarities derived from two species with independent ancestors. Eg. a bat's wing and a human's hands

5 Multiple choice questions

  1. the process in which a single lineage diversifies into a number of species
  2. where two somewhat related species eventually form a new species
  3. a hypothesis that speciation can result from selective pressures favoring different phenotypes within a population without geographic isolation as a factor
  4. the shown trait
  5. where a single phenotype is favored, causing the allele frequency to continuously shift in one direction

5 True/False questions

  1. natural selectionwhere a single phenotype is favored, causing the allele frequency to continuously shift in one direction

          

  2. balanced polymorphisma steady state in which two or more alleles coexist in a population.

          

  3. reproductive isolationdriving force behind sympatric speciation extreme values for a trait are favored over intermediate values. E.g.: large nose rather than medium sized nose

          

  4. homozygouscarries genes and appears during cell division

          

  5. morphologythe form and structure of an organism
