Ancestral gene flow shaped the singular origin of the Amazon molly

The paper investigates the origin of asexuality in the Amazon molly, showing that ancestral introgression between parental species contributed to its unique genomic makeup.

Hybridogenetic reproduction of Pelophylax water frogs from different R-E hemiclonal population systems from Eastern Ukraine: selective mortality, clonal and ploidy diversity

Siverskyi Donets water frog systems lacking P. lessonae split into diploid-only and diploid-plus-triploid hybrid types, with clonal, low-diversity L-genomes and steep tadpole-to-adult loss of P. ridibundus.

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.

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.
