Sheep populations from New Zealand are: Finn, Primera, Texel, “Other Dual Purpose” (DP), Lamb Supreme (LambSup), and “Other Terminal Sire” (TS). Ntotal: total number of segments. Min SNPs: minimum number of single nucleotide polymorphisms (SNP) in a ROH, calculated as suggested by Lencz et al. (2007). nSEG: average number of segments for the individual declared homozygous. Kbi: average size of total homozygous segments per individual. Kb, average of total number of kb contained within homozygous segments. nSNP, average number of SNPs in run. Density, inverse SNP density in Kb/SNP. Phom, proportion of sites homozygous. Minimum and maximum values are shown inside brackets.
