Using Drosophila pigmentation traits to study the mechanisms of cis-regulatory evolution

One primary agenda of the developmental evolution field is to elucidate molecular mechanisms governing differences in animal form. While mounting evidence has established an important role for mutations in transcription controlling cis-regulatory elements (CREs), the underlying mechanisms that translate these … Continue reading
