Sex Chromosome Turnover and Structural Interspecific Genome Divergence Shapes Meiotic Outcomes in Hybridizing Cobitis

The paper presents chromosome-level genome assemblies for three hybridizing Cobitis species to study hybrid sterility and asexuality, revealing structural variation and sex chromosome divergence.

Zombie Gene Flow: Asexual Hybrids Mediate Extensive Genomic Introgression from Extinct Species Into Their Sexual Parent

The paper shows asexual hybrids mediate genomic introgression from an extinct species into their sexual parent, challenging the view of asexual lineages as evolutionary dead ends.

Mitochondria as Indispensable Yet Replaceable Components of Germ Plasm: Insights into Primordial Germ Cell Specification in Non-Teleost Sturgeons

This study shows mitochondria are essential for primordial germ cell formation in sturgeons, but their function is not restricted to germ plasm origin.

Clonal gametogenesis is triggered by intrinsic stimuli in the hybrids germ cells but is dependent on sex differentiation

The paper investigates the triggers of clonal gametogenesis in hybrids, finding that it is initiated by intrinsic signals in hybrid germ cells but requires a female gonadal environment for execution.
