Do all birds' sex chromosomes follow the same canonical one-way direction of evolution? We combined cytogenetic and genomic approaches to analyze the process of the W chromosomal differentiation in two selected Passeriform species, named the Pale-breasted Thrush Turdus leucomelas and the Rufous-bellied thrush T. rufiventris. We characterized the full catalog of satellite DNAs (satellitome) of T.

Article Synopsis
- Charadriiformes is a diverse avian order with over 390 species, including the wattled jacana, which has a unique ZZ/ZW sex chromosome system and intricate karyotype.
- Researchers characterized satellite DNAs (satDNAs) at molecular and cytogenetic levels, identifying 11 distinct satDNAs that are primarily located on microchromosomes and the W chromosome.
- Additionally, the study highlighted a significant accumulation of telomeric signals and found (GA) microsatellites as the only ones with positive hybridization, enhancing our understanding of genomic organization in birds with high chromosomal variation.
