Expanded centromere DNA repeats violate Mendel’s law of segregation by preferentially segregating to the egg in animals and plants. Using oocytes collected from hybrid mice, Walton et al. show that th...

In general, the kinetochore position and the sister-chromatid cohesion site are spatially linked. Here, the authors find a meiosis-specific distal cohesion site decoupled from the kinetochore in Perom...

Female reproductive aging is accompanied by a dramatic rise in the incidence of egg aneuploidy. Premature loss of chromosome cohesion proteins and untimely separation of chromosomes is thought to unde...

Meiosis is an essential cell division for sexual reproduction and fertility across eukaryotes. It involves a series of tightly regulated processes, including entry into meiosis, pairing of homologs, …

Background Centromeres depend on chromatin containing the conserved histone H3 variant CENP-A for function and inheritance, while the role of centromeric DNA repeats remains unclear. Retroelements are...

Natural selection in the cave habitat has resulted in unique phenotypic traits (including pigmentation loss and ocular degeneration) in the Mexican tetra Astyanax mexicanus, considered a model species...

Drive mechanisms in B chromosome systems remain unclear. Here, the authors assemble the rye B chromosome pseudomolecule, identify candidate trans-acting, drive-controlling factors of the B chromosomal...

Nature Communications - Unlike most eukaryotes, Luzula sylvatica assembles holocentromeres along the entire chromosome length. Here, the authors combine genome assembly, epigenetic and cytogenetic...
