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
