Genuinely one of the most important and interesting papers I have been a part of! Relevant to fundamental questions regarding the predictability of adaptation, as well as the applications of genomic data. Congrats to @j-smiley-rhodes.bsky.social and all co-authors for such a masterpiece!
Thrilled to finally share the magnum opus of my PhD that focuses on the genetic basis of evolutionary change! Specifically, we know we can map the genetic basis of a trait, but can we tell which genes will underlie the trait shift when it evolves? doi.org/10.1101/2025...
High-resolution mapping of a rapidly evolving complex trait reveals genotype-phenotype stability and an unpredictable genetic architecture of adaptation
The extent to which adaptation can be predicted, particularly for traits with complex genetic bases, is unknown. Here, we leveraged a model complex trait, model species, and high-powered longitudinal ...

New paper from the lab: we’re using long-read sequencing to disentangle isoform complexity at allele-specific loci 🧬💡
Here, we combine the PacBio Iso-Seq workflow with the established WhatsHap phasing approach to assign long reads to the correct allele in polymorphic F1 mouse hybrids.

They might not be giants: The genetics behind why some fish remain tiny
Imagine you are a kind of fish called a goby, part of a huge family of more than 2,000 species. Maybe you're of average size for a goby, about three to four inches long.

Always a special moment when a PhD student publishes their first paper for their thesis. This one was expertly supervised by senior author @jpverta.bsky.social and highlights the regulatory potential of lncRNAs in reproductive biology and maturation age variation in salmon
Surprise 🤗 So many uncharacterized transcripts in Atlantic salmon, including super interesting long non-coding RNAs!
