BIO 182Bang, Michel(Christofer)2013 SpringWeek 12Lecture 12February 13Populations are not evolving1. The organism is diploid2. Reproduction is sexual3. Generations are non-overlapping4. Mating is random5. Population size is very large6. Migration in negligible7. Mutation can be ignored8. Natural selection does not affect the alleles under consideration 9. The alleles under consideration are not on the sex chromosomesHardy-Weinberg equilibrium is only met when:1. There are NO mutations2. There is NO gene flow3. The population must be VERY large4. Survival is RANDOM5. Reproduction is RANDOMIn Real Life: 1. Mutations occur at a slow but steady rate in all known populations2. Many organisms enter and leave populations3. Most populations are not large enough to be unaffected by random changes in allele frequencies4. Survival is virtually never random5. Reproduction in organisms that can choose their mates is also virtually never random*Alleles Frequency: p + q = 1These notes represent a detailed interpretation of the professor’s lecture.
