Dm-Dy: between-species pairwise comparisons of insertions that belong to orthologous families from D. melanogaster and D. yakuba, and so on. Low KS: numbers of families that display a level of synonymous divergence (KS) lower than the 2.5% quantile of the distribution of KS values for the nuclear genes of the hosts. N: number of orthologous families analyzed. F: fraction of families with lower KS than expected under neutral assumptions. |
