5 Matching questions

  1. fitness
  2. vestigial structures
  3. species
  4. polygenic traits
  5. artificial selection
  1. a traits that are controlled by two or more genes
  2. b how well an organism can survive and reproduce in its environment
  3. c inherited from ancestors but have lost much or all of their original function due to different selection pressures acting on the descendant
  4. d nature provides the variations, and humans select those they find useful
  5. e a population or group of populations whose members can interbreed and produce fertile offspring

5 Multiple choice questions

  1. when allele frequencies change as a result of the migration of a small subgroup of a population
  2. body parts that share common function, but not structure
  3. form of reproductive isolation in which two populations are separated by geographic barriers such as rivers, mountains, or bodies of water, leading to the formation of two separate subspecies
  4. the study of where organisms live now and where they and their ancestors lived in the past
  5. separation of a species or population so that they no longer interbreed and evolve into two separate species

  2. allele frequencywhen allele frequencies change as a result of the migration of a small subgroup of a population

          

  3. homologous structuresstructures that are shared by related species and that have been inherited from a common ancestor

          

  4. adaptationany heritable characteristic that increases an organism's ability to survive and reproduce in its environment

          

  5. natural selectionthe process by which organisms with variations most suited to their local environment survive and leave more offspring
