Kind: research · Impact: medium

## In brief

- A recessive loss-of-function allele causing lethal multi-organ pathology was found in a source population used for a lynx reintroduction programme.
- The source population was bottlenecked, and the allele has increased in frequency there.
- The study was published online in Nature Ecology & Evolution on 13 November 2026.

## Why it matters

Reintroduction programmes that draw on small, bottlenecked source populations can carry harmful recessive alleles unnoticed, which can later reduce survival of released animals.
