WebFisher’s model predates the next mathematical treatment of the runaway process (O’Donald 1962) by 30 years and the first quantitative genetic treatment (Lande 1981) by half a century. It is consequently of great interest what his model says and to what extent it anticipates future work. Here, we dissect Fisher’s model in detail.
