Fig. 2.

Comparative analysis of the PIMT ARId from two midges. (A) ML tree with bootstrap testing (100 replicates). Pv, P. vanderplanki; Pp, P. pembai, Pn, P. nubifer. Red color shows the clade under positive selection; blue color shows P. pembai PIMTs; orange color shows P. vanderplanki PIMTs. (B) Nucleotide diversity along P. vanderplanki PIMT ARId; (C) Comparison of gene order in the two ARId. Black lines represent homologous genes; (D) Nucleotide diversity along the P. pembai PIMT ARId. Gray color shows the zone of selective sweep found by Pool-hmm. Coverage curve shown in (A, D) is based on mapping of Tashan nabai population genomic data of P. vanderplanki and Chikopa population genomic data of P. pembai. ω₁ stands for the foreground ratio, and ω₀, for the background ratio.
