- Reposted by Thomas Lesaffre 🌱New paper with @vsudbrack.bsky.social. Using pop gen modelling, we show that partial selfing makes selection on tandem repeats more efficient, reducing the associated load across different scenarios.

This is thought to drive balancing selection and maintain genetic polymorphism. We challenge this view in our recent paper : 🔗 doi.org/10.1093/evlett/qrae059
