WebNov 2, 2024 · Inbreeding can be identified and quantified through runs-of-homozygosity (ROHs), which are long contiguous tracts of identical haplotypes inherited from a common ancestor [ 22 ]. We calculated FROH, an accurate measure of inbreeding, as the summed lengths of ROHs greater than 100 kb divided by the total genome size. WebInbreeding depression - Understanding Evolution.
