5 Matching questions

  1. morphological species concept
  2. microevolution
  3. allopatric speciation
  4. ecological species concept
  5. species
  1. a A definition of species in terms of ecological niche, the sum of how members of the species interact with the nonliving and living parts of their environment.
  2. b The formation of new species in populations that are geographically isolated from one another.
  3. c Evolutionary change below the species level; change in the allele frequencies in a population over generations.
  4. d A population or group of populations whose members have the potential to interbreed in nature and produce viable, fertile offspring, but do not produce viable, fertile offspring with members of other such groups.
  5. e A definition of species in terms of measurable anatomical criteria.

5 Multiple choice questions

  1. A geographic region in which members of different species meet and mate, producing at least some offspring of mixed ancestry.
  2. A definition of species as the smallest group of individuals that share a common ancestor, forming one branch on the tree of life.
  3. Definition of a species as a group of populations whose members have the potential to interbreed in nature and produce viable, fertile, offspring, but do not produce viable, fertile offspring with members of other such groups.
  4. A reproductive barrier that prevents hybrid zygotes produced by two different species from developing into viable, fertile adults.
  5. Offspring that results from the mating of individuals from two different species or from two true-breeding varieties of the same species.

5 True/False questions

  1. autopolyploidAn individual that has more than two chromosome sets that are all derived from a single species.

          

  2. allopolyploidAn individual that has more than two chromosome sets that are all derived from a single species.

          

  3. speciationAn evolutionary process in which one species splits into two or more species.

          

  4. reproductive isolationEvolutionary change below the species level; change in the allele frequencies in a population over generations.

          

  5. punctuated equilibriaIn the fossil record, long periods of apparent stasis, in which a species undergoes little or no morphological change, interrupted by relatively brief periods of sudden change.
