This study analyzes ancient genomes from Roman and early medieval Britain to uncover population history, ancestry shifts, and selection patterns shaping modern genetic diversity.

The paper shows that mismatch repair (MMR) suppresses meiotic class I crossovers (COs) at regions of high sequence divergence in yeast, linking MMR to CO distribution and speciation.

The paper shows that DNA double-strand breaks (DSBs) during meiosis often occur in clusters with periodic spacing, challenging the idea that DSBs are isolated events.

This study investigates the distinct roles of Mec1 and Rad24 in meiotic recombination, showing that Mec1 affects DSB trans-interference and CO pathway distribution, while Rad24 influences interference through CO number reduction.
