BIO 2133 Lecture Notes - Lecture 2: Allele Frequency, Genetic Drift, Allele
Document Summary
The above equation is for a gene with two alleles. Could you derive the hardy-weinberg equation for a gene with three alleles? (p + q + r)2 = p2 + 2pq + p2 + 2qr + r2 + 2rq. Since there are 3 alleles, there must be 3 variables in the equation and if you expand it, then that is how you get the longer version of the equation. Leave all default settings and run two or three simulations by pressing ctr =. Paste the results for one simulation run and refer to the displayed results to explain how population size modulates the extent of genetic drift. Deme_simulator version 2. 0 on the default settings with drift option that is set to on . Genetic drift alone will not lead to the disappearance of some alleles. The impact of population size on variability shows that the higher the population, the lower the variability on the frequencies of alleles.
