5 Matching questions

  1. genetic drift
  2. reproductive isolation
  3. what's a nucleotide composed of?
  4. founder effect
  5. meiosis
  1. a the process of cell division in which haploid gametes (eggs and sperm) are creatred
  2. b occurs when a new colony is started by a few peope from the original population. Not much diversity, usually mutations.
  3. c a relationship between two populations in which there is no gene flow between them
  4. d the change in frequency of a gene do to randomness
  5. e a phosphate-sugar base

5 Multiple choice questions

  1. a diploid organism whose chromosomes have two copies of the SAME allele. Opposite of heterozygous
  2. where two somewhat related species eventually form a new species
  3. the process of division of normal body cells through which new diploid cells are created
  4. one of two or more alternative forms of a gene
  5. the process in which a single lineage diversifies into a number of species

5 True/False questions

  1. balanced polymorphismwhere two somewhat related species eventually form a new species

          

  2. disruptive selectiondriving force behind sympatric speciation extreme values for a trait are favored over intermediate values. E.g.: large nose rather than medium sized nose

          

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

          

  4. punctuated equilibriumopposite of punctuated equilibrium

          

  5. anagenesiswhere two somewhat related species eventually form a new species
