Chromosome‐Level Genome Assemblies of Two Softshell Turtles with ZZ/ZW Provide Insights into TE‐Driven Recombination Suppression in Sex Chromosomes

Integrative Zoology, EarlyView.
This study presents the first genomic identification and characterization of ZW sex chromosomes in two soft‐shelled turtle species through genome assembly and resequencing. We reveal the structural organization of ZW chromosomes, identifying both pseudoautosomal regions (PARs) and differentiated regions.
