Color Differences Between The Sexes Driven By Simple Molecular Mechanisms Hello everyone,
have you ever wondered how male and female can look different from each other despite sharing the same genes? Recently, a study was published that looked at one particularly common trait in birds: dichromatism (where males and females have plumage of different colors, color patterns or ornamentation). This study found that this sex difference in birds -- even when it's a dramatic difference as seen in eclectus parrots -- is driven by surprisingly simple molecular mechanisms -- and explains how dichromatism arises quickly amongst birds.
