Additive genetic effects triggered by flower color variation of I. potaninii. (A) Annotated number differences occur in Gene Ontology between two color morphs of I. potaninii. (B) Phylogenetic analyses from 6,589 strict single-copy orthologs groups. Most single copy orthologs support yellow-flowered I. potaninii as sister to purple-flowered I. potaninii (Topology 1, 86.72%). (C) Protein evolution of 6,589 single copy orthologs among purple-flowered I. potaninii, yellow-flowered I. potaninii, I. loczyi, and I. atropurpurea. Differentially evolving genes with higher ωyellow than ωpurple are indicated by yellow points
