The paper identifies a novel mechanism for autopolyploidization in yeast called SEM, demonstrating triploid and tetraploid formation through postmeiotic endoreplication and mating.

The paper shows that absence of Red1 and Hop1 recruitment prevents meiotic recombination on a chromosome arm containing the sex locus in Lachancea kluyveri, affecting genome evolution and fitness.

The paper directly determines meiotic crossovers in fission yeast S. pombe, confirming the absence of crossover interference and revealing co-variation in CO numbers across chromosomes.
