Reposted by Valentina PeonaSamuel Lampa @smllmp.bsky.social · 07/11/2025This has been a fantastic course, very well done @valentinapeona.bsky.social and @ritarebollo.bsky.social ! 🙌 Looking forward to continue diving into the field 😊 132
Reposted by Valentina PeonaReto Burri @reto-burri.bsky.social · 17/10/20253/9 The black-or-white throat polymorphism is explained by the interaction of a transposable element (an LTR retrotransposon) upstream ASIP with ASIP coding variation. Mantle and neck side coloration is encoded by additive effects of regulatory variants upstream ASIP. 142

To address this question, we inferred the genetic architecture of convergent plumage coloration and its evolutionary history in wheatears.science.orgA mosaic of modular variation at a single gene underpins convergent plumage colorationThe reshuffling of genomic variation from multiple origins is an important contributor to phenotypic diversification, yet insights into the evolutionary trajectories of this combinatorial process and ... 510353
