Haldane) set the theoretical foundations for much of what became the field of population genetics (Provine, 1971).Both Wright (1931) and Fisher (1922, 1958) … WebJan 25, 2011 · Fisher's fundamental insights were essentially ignored. In fact it was not until some 50 years later that Lande showed that Fisher's logic was correct, and that accelerating evolution of preference and trait could occur when the strength of natural selection on the male trait was relatively weak and the genetic correlation between …

As the number of gene loci that are variable increases and as the number of alleles at each locus becomes greater, the likelihood grows that some alleles will change in frequency at the expense of their alternates.
