Distribution of CYP4G1-type and CYP4G15-type sequences in Neoptera.

The CYP4G appear to have evolved from a CYP4C ancestor. Lineages lacking one of the two genes are shown in stippled line. B indicates gene duplications in the lineage, while D means gene loss. This is Figure 6 of Feyereisen, 2020 where full details can be found.The insect phylogeny follows Misof et al.,2014.
