  1. Insertion time of each cluster of ERVs was estimated by two methods: (1) Phylogeny based substitution rate: LTR divergence / (distance of 3ā€² LTRsā€‰+ā€‰dist of 5ā€² LTRs) [24] and (2) using the LTR divergence and fixed substitution rate of 2.3x10-6 and 5x10-6[14]. Btau, Bos taurus; Bind, Bos indicus; Bgru, Bos grunniens. Clusters of ERVs are showed in FigureĀ 1. NA, the phylogenetic relationship of LTRs of clusters of ERVs did not follow the species relationship.
