Stable but turbulent: the two faces of the germline-restricted chromosome of passerine birds

2026-02-18

Abstract excerpt

Germline-restricted chromosomes (GRCs) are essential, supernumerary chromosomes that undergo programmed elimination in somatic cells and are only retained in the germline. Despite their recurrent emergence across animals, their genetic composition, function and evolution remain poorly understood. Here we present the most complete and contiguous GRC assemblies, including one nearly telomere-to-telomere GRC assembly...
