The population genetics 's view of recombination parameters is not useful to individual IBD models of transmission of genetic material to the grand-offspring generation. Sam Karlin and Liberman proposed the idea of "multilocus feasible"models of recombination mappings. This allows for fitting recombination to several loci while keeping the additivity of the IBD segments in a chromosome. However, few models display the property. Noticeably Haldanne's, who does not consider interference and Goldgar and Fain, which has a complicated parametrization. Is there any other model that is more manageable than Goldgar's and is amenable to account for interference (unlike Haldane's)?
