Ancestral Chromatin Configuration Constrains Chromatin Evolution on Differentiating Sex Chromosomes in Drosophila
Fig 2
We used 6189 orthologous gene pairs from 9 Diptera species and constructed a phylogenomic tree. Although the bootstrap value at the ancestral node of D. busckii and D. albomicans is low, D. busckii is grouped with high confidence within the Drosophila subgroup instead of as a sister group to all Drosophila species, as previously hypothesized [16,30].
