@mirandaconcolor.bsky.social et al. studied the regulation of sexual dichromatism in cardinals, finding that BCO2 upregulation is the main mechanism underlying reduced pigmentation in females. 🔗 academic.oup.com/gbe/article/... 📷 Geoffrey E Hill #societyjournal #evolution
GBE | Not All Roads Lead to Red: The Genetics of Sexual Dichromatism in the Northern Cardinal (Cardinals cardinalis)

A diagram illustrating the genetics of sexual dichromatism in northern cardinals (Cardinalis cardinalis). On the left, a female cardinal is shown, with arrows pointing to explanations of genetic factors: incresed BCO2 gene expression in feather follicles reduces carotenoid coloration, increased melanin-related gene expression influences feather color, and and equal sign indicating similar CYP2J19 transcription levels in feathers between the sexes. On the right, a male cardinal is shown, with arrows indicating observed higher ketocarotenoid concentration measured via HPLC, increased expression of CYP2J19 in the liver and TTC39B in feathers, and increased sex-hormone regulatory gene expression contribute to red coloration. The caption notes that dichromatism in northern cardinals is likely shaped by both sexual and natural selection, leading to sexually-antagonistic gene expression
