The paper presents complete GRC assemblies from passerine birds, revealing their composition, evolution, and dynamic nature despite their stability in the avian karyotype.

The paper identifies a centromeric satellite repeat in songbirds and shows it is absent from the germline-restricted chromosome (GRC), suggesting sequence changes underlie its programmed elimination.

The paper identifies germline-restricted chromosomes (GRCs) in 6,700 passerine species, showing rapid evolution and functional gene retention despite programmed DNA elimination.

This study investigates the mechanisms and timing of programmed DNA elimination in songbirds, identifying key cellular and epigenetic processes involved in the removal of the germline-restricted chromosome from somatic cells.

The paper shows hybrid asexuality can act as a primary reproductive barrier in speciation, emerging before other postzygotic incompatibilities in Cobitis loaches and other fish species.
