We consider a one-dimensional population genetics model for the advance of an advantageous gene. The model is described by the semilinear Fisher equation with unbalanced bistablenon-Lipschitziannonlinearityf(u). The “nonsmoothness” offallows for the appearance of travelling waves with a new, more realistic profile. We study existence, uniqueness, and long-time asymptotic behavior of the solutionsu(x,t),. We prove also the existence and uniqueness (up to a spatial shift) of a travelling waveU. Our main result is the uniform convergence (for) of every solutionu(x,t) of the Cauchy problem to a single travelling waveas. The speedcand the travelling waveUare determined uniquely byf, whereas the shiftis determined by the initial data.
