From: Recombination facilitates neofunctionalization of duplicate genes via originalization
Dynamic changes of chromosomal haplotype frequencies for gene duplication during neofunctionalization under strong positive selection. Assume s = 0.01 and μneo = 10-6. In subplot A, are numerical results under the DNR selective model; in subplot B, numerical results under the HI selective model. Solid and dashed curves are numerical results for linked and unlinked gene duplication, respectively. Red, green and blue curves are numerical results for frequencies of chromosomal haplotypes "00", "02" and "20", corresponding to x0, x1 and x2, respectively. In subplots A and B, for linked gene duplication, curves of x1 and x2 are completely coincident.
