The passage around this formula
…of a mutant gene’s ultimate fate was “first treated quantitatively by Fisher (1922),” with “equivalent results” reached independently by Haldane in 1927 and Wright in 1931 [ 7 ] . Kimura wrote the fixation probability u(p,t) as the solution of what he explicitly called the Kolmogorov backward equation, subject to the boundary conditions u(0,t)=0 and u(1,t)=1 — an allele already lost stays lost, one already fixed stays fixed [ 7 ] . That boundary structure is doing real work: it is the diffusion equation’s way of…
