Mating systems
- HW assumptions: random mating,
- negative (avoid) and positive (preferred) selection
Population size
- assumption: infinite smaller populations will violate
HW more
Mutation
- mutations change frequencies of alleles - this is usu
what starts an allele in the first place
Migration
- assumption: no migration else, this will dilute
Drift
- result of selection selective advantage spreads
Selection
- genocide, etc
homo: (Nqo2waa) * 2
het: N2poqowAa
Note: this applies only to the mutant allele; we hold the other
fitness value w constant (wa=1) as the other varies (wA=?)
Note: to compare,
brother x sister = 0.25
self x self = 0.5
