If selection is only strong enough to overcome the random effects of genetic drift when Ne s >> 1, how large a selection coefficient s is needed for a beneficial new mutation to reliably evolve to higher frequency in a typical human population? Ne in human population: 10,000 |s| > 1/Ne |s| > 1/10,000 |s| > 0.0001 A selection coefficient of 0.0001 would be needed. Consider the following descriptions of genetic loci, and predict what dN/dS ratio you would expect to see for each on...
