Assessment of runs of homozygosity islands and estimates of genomic inbreeding in Gyr (Bos indicus) dairy cattle

Table 2 Descriptive statistics of the pedigree-based inbreeding coefficient (F_PED) and genomic inbreeding coefficients based on runs of homozygosity (F_ROH) for different lenghts (F_{ROH1–2 Mb}, F_{ROH2–4 Mb}, F_{ROH4–8 Mb}, F_{ROH8–16 Mb}, and F_{ROH > 16 Mb}) for genotyped animals (n)
