WebThe linkage relationships should always be verified by segregation analysis, since polymorphic regions, unlinked to the trait, also could be present in the introgressed NIL … WebApr 15, 2024 · We then combined individual profiles of introgressed windows to estimate the fraction of introgressed archaic tracts in each population (F archaic), as the fraction of haplotypes for which a window was identified as introgressed. The inferred fraction of introgressed archaic tracts was finally averaged in nonoverlapping 50-kb windows …
