Table 3.
ROH islands identified in Italian chicken breeds represent the genomic regions of extended homozygosity. Gallus gallus chromosome number (GGA), number of SNP per region (no. of SNPs), start and end points (Start/End), length of region (length in bp), genes inside the islands (Genes), and quantitative trait loci (QTLs) are reported.
