Inference of Ancestral Recombination Graphs through Topological Data Analysis
Fig 8
Barcode ensemble of two divergent sexually-reproducing populations.
The case in (A) assumes the two populations are completely isolated. All recombination events present in the barcode ensemble involve genetically close parental gametes. The case in (B) considers a small migration rate between the two populations. Some of the recombination events present in the barcode ensemble involve genetically distant parental strains, leading to larger death times ϵd in the barcode ensemble. The total number of detected recombination events is similar in both cases and uniform across the entire genome. Intervals with the location of the recombination breakpoints are indicated for each recombination event, where positions refer to segregating sites.
