  1. The numbers in parentheses are normalized by sample counts except that the lengths in parentheses are average lengths normalized by CNV counts. aAt sample level, each sample has 7.09 (3666/517) CNVRs averagely and 6.23 (2256/362) for Taurine, since there are 4 taurine individuals without identified CNVs; b These numbers are nonredundent CNVR counts. c 278 CNVRs are unique to one sample while 404 CNVRs are shared by at least 2 individuals or breeds and 18 of 404 multiple events have frequency >5%; d Besides 370 loss and 216 gain CNVRs, there are 96 CNVRs containing both loss and gain events; e Outgroup animals are not included in the total counts for CNV and CNVR.
