BSCI205 Lecture #7 9/16/2010 1 Relaxing Assumptions of the Hardy-Weinberg Principle 1. There is no mutation 2. Mating among individuals is random (-> if not, inbreeding) 3. The population is infinitely large (-> if not, random genetic drift) 4. Individuals are not moved into or out of the population (-> if not, gene flow or migration) 5. All individuals have equal probabilities of survival and of reproduction (-> if not, natural selection) Inbreeding Panmictic population : a population in which individuals mate at random Inbreeding : the phenomenon in which certain individuals in a population are more likely to mate with relatives than with non-relatives Self-fertilization / Selfing : extreme form of inbreeding Freeman & Herron, Evolutionary Analysis, 4th edition, Fig 7.25
