Bulldog ROH

Inbreeding tends to produce runs (blocks) of homozygosity (ROH) on the chromosomes. Over time, the crossing-over of chromosomes during meiosis can split up blocks of homozygosity, so the largest blocks are likely to be the most recent inbreeding and smaller blocks reflect older inbreeding. ROH are used to estimate inbreeding from SNP data.
