Document Summary
Allele frequency, how to generate it, factors that affect it: allele frequency the frequency with which alleles of a particular gene are present in a population. The frequency can change from generation to generation: can be generated with the hardy-weinberg equation, affected by genetic drift. Hardy-weinberg equation p2 + 2pq + q2 = 1: p = dominant allele a , q = recessive allele a , p+q=1. Conditions for genetic equilibrium: the population is large enough to not be affected, no gene flow, no mutations, random mating, no natural selection. Theory of natural selection: acts on genetic diversity in populations and is the major driving force in evolution, differential reproduction shown by some members of a population that is the result of differences in fitness. Spontaneous mutation: result from dna replication errors. Why do you use morphs exercise: to show how random events could lead to ordered structures. Induced mutation is brought about by a mutagen.
