  2. chromosomes
  3. homologous traits
  4. natural selection
  5. pleiotropy
  1. a carries genes and appears during cell division
  2. b genes that influence multiple traits
  3. c the process that produces adaptation
  4. d structural similarities derived from two species with independent ancestors. Eg. a bat's wing and a human's hands
  5. e the process in which a single lineage diversifies into a number of species

5 Multiple choice questions

  1. the shown trait
  2. many genes?
  3. a spontaneous change in the chemical structure of DNA
  4. a steady state in which two or more alleles coexist in a population.
  5. 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

5 True/False questions

  1. genetic driftthe change in frequency of a gene do to randomness

          

  2. diploidthe process of division of normal body cells through which new diploid cells are created

          

  3. bottleneck effectoccurs when a population endures a natural disaster and alleles are greatly reduced in diversity

          

  4. meiosisthe process of division of normal body cells through which new diploid cells are created

          

  5. parapatric speciationa hypothesis that speciation can result from selective pressures favoring different phenotypes within a population without geographic isolation as a factor
