  5. homozygous
  1. a structural similarities derived from two species with independent ancestors. Eg. a bat's wing and a human's hands
  2. b many genes?
  3. c 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
  4. d a diploid organism whose chromosomes have two copies of the SAME allele. Opposite of heterozygous
  5. e ex: height in humans, birthweight

5 Multiple choice questions

  1. the process of division of normal body cells through which new diploid cells are created
  2. a FEATURE of an organism CREATED by the process of natural selection.
  3. the form and structure of an organism
  4. evolution of populations within a species
  5. carries genes and appears during cell division

5 True/False questions

  1. pleiotropythe shown trait


  2. What are the differences between DNA and RNADNA is double stranded while RNA is single stranded, DNA has only a nucleus but RNA can have a nucleus or a cytoplasm, the main ingredient in DNA is Thymine while in RNA it's Uracil.


  3. natural selectionthe process that produces adaptation


  4. phenotypethe genetic makeup of a trait


  5. parapatric speciationtwo-step process in speciation where selection causes the differentiation of geographically separate, isolated populations of a species and the populations become reproductively isolated as well
