The paper presents whole genome sequences of two elasmobranchs, analyzing genome size dynamics and genomic architecture, revealing correlations between chromosome size, repetitive elements, and gene duplication patterns.

The paper investigates the evolutionary and expression dynamics of meiotic cohesin genes in teleost fish, showing that whole-genome duplication and regulatory rewiring drive sex-biased expression patterns.

This paper develops molecular sexing methods for sharks using sex-linked DNA markers to address sex identification challenges in forensic, archival, and developmental samples.

This study identifies the oldest vertebrate sex chromosomes in sharks and rays, revealing a unique dosage-dependent sex determination mechanism distinct from other vertebrates.
