Probability of allele fixation

WebbIn simulated adaptation under this model, the population frequently reaches fixation for the mutationally favored allele, even though it is not the most fit option. The form of the model is agnostic with respect to whether the biases are mutational or developmental. WebbFixation Probability in a Haploid-Diploid Population Genetics Oxford Academic Abstract. Classical population genetic theory generally assumes either a fully haploid or fully …
