Extended Data Fig. 7: Repeat density across fused chromosomes and their unfused homologues in pairs of sister species.
From: Comparative genomics reveals the dynamics of chromosome evolution in Lepidoptera
a–c, Repeat density in fused chromosomes in one species, compared to the repeat density of the unfused orthologous chromosomes in a sister species. As each fusion is present in one species and absent in the other sampled species from the same genus, they are likely very recent fusions. Agrochola circellaris, compared to A. macilenta (a), Dendrolimus kikuchii compared to D. punctatus (b) and Agonopterix subpropinquella and A. arenella (c). Repeat density is plotted along each chromosome in 100 kb windows, where the chromosome position is scaled to proportional length by dividing by genome size. Lines represent LOESS smoothing functions fitted to the data. Points are coloured by Merian element. Blue dashed lines indicate the fusion point along fused chromosomes.
