A while back (maybe 3-4 years?) there was a paper on common misconceptions of the genetics of various traits. One of them was eye colour in humans. I have lost this reference and can't find it anywhere. Does anyone recognise what I mean?

Interested in host-associated microbiomes? Attending @eseb2025.bsky.social? Then come check out Symposium S07 on Monday August 18th and hear all about how microbiomes contribute to adaptation. Gut microbiomes, climate change, thermal physiology, behaviour, invasion biology, blood-feeding, and more!

Dr Eva van der Heijden (first PhD in my group, not on Bluesky) finished her PhD with flying colours and a new hat! The hat represents her PhD with CRISPR DNA, butterflies, a tiny net, GWAS dots, etc. What a great day of celebration! @sangerinstitute.bsky.social @camzoology.bsky.social

Delighted to share our new review paper onlinelibrary.wiley.com/doi/10.1111/.... This was a whole-lab effort for my group ~2021, and these students were a dream team 🤩 (yes it took us 4 years...but I'll take credit for that...turns out having a baby in a pandemic slows things down 😜).

Looking without bias is very hard to do. We want to “let the data do the talking” but data must be interpreted against backgrounds that are not bias-free.
I want to tell you about an experiment showing how when looking at a plot, we come with bias that frames our perception.🧵⬇️
