1. Understand the intimate relationship between populations and diversity R.  Determine  (using the HW equation) if a population is in Hardy-Weinberg equilibrium 2. Understand that not all genes in all populations are in HW equilibrium A.  List  the four processes that shift allele frequencies in populations through time E.  Define  biological evolution G. When prompted with one of the conditions of the H-W Principle,  describe  (in your own  words) why a population cannot be in H-W equilibrium without it 1. Understand fitness in the context of natural selection A.  Define  fitness in the context of natural selection B. E.  Contrast  fitness (in the context of natural selection) with common-language  definitions of fitness (e.g., physical fitness)

Hardy-Weinberg Equilibrium genotype frequencies and allele frequencies do not change Expected homozygous dominant =  p 2 Expected heterozygous =  pq + pq =  2pq Expected homozygous recessive =  q 2 Not just next generation, but  EVERY  generation HW predicts that neither  genotype  nor  allele  frequencies will change over time  (equilibrium  = steady state ) 2E Biological evolution:  a change in  allele  frequencies  within a population over time

Hardy-Weinberg Equilibrium conditions that must be met 1. No natural selection:  All combinations of parental  genotypes produce equal numbers of offspring 2. No genetic drift:  The frequencies of alleles in gametes
