Genomic imprinting is a barrier to parthenogenesis in mammals.

abstract：:Transposable elements (TE) constitute one of the most variable genomic features among vertebrates, impacting genome size, structure, and composition. Despite their important role in shaping genomic diversity, they have mostly been studied in mammals, which display one of the least diverse genomes in terms of TE divers...
