BIO 258 Notes
WEEK #6.
GENETICS AND MICROEVOLUTION (continued)

• Origin of variation: sources of variability. (Futuyma ch. 10; Minkoff Ch. 7; E13).
  • Mutations, chromosomal variations
  • Variations in phenotypic expression
  • Chromosome numbers and chromosomal family trees
  • Recombination and recombination systems
  • Sexual & asexual reproduction
• Genetics variation in populations. (Futuyma ch. 9; Minkoff Ch. 8; E14).
• Hardy-Weinberg equilibrium __________
• Departures from Hardy-Weinberg:
  • mutations (unbalanced)
  • migrations
  • nonrandom mating (assortment, inbreeding)
  • genetic drift
  • natural selecgtion (details next week)
• Genetic drift (Futuyma ch. 11)
  • in general
  • rare alleles
  • bottleneck effects
  • founder effects
  • example: Dunkers
  __________
• Genetic systems (Futuyma ch. 21)
  • asexual reproduction
  • sexual reproduction
  • openness of recombination
• Population growth. (Minkoff Ch. 9; E15).
  • exponential growth and r
    dN/dT = rT,    
  • logistic growth and K
