Phase separation determining meiotic interference-sensitive meiotic crossover formation

In sexual reproduction, meiosis creates new combinations between homologs and diversifies the genetic information among gametes and progenies. Most meiotic crossovers (COs) are mediated by a group of ZMM factors, including HUMAN ENHANCER of INVASION-10 (HEI10), which is suggested to concentrate at CO…
