The paper quantifies mating strategies in yeast gametes, revealing a reproductive hierarchy where sibling gametes have divergent mating trajectories and temporal heterogeneity shapes compatibility.

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 repeated loss of mating-type switching in yeast led to heterothallism, polyploidy, and increased heterozygosity across diverse environments.

The paper measures mutation rates in yeast colonies and finds that double mutations occur at higher rates than expected, suggesting transient mutator phenotypes contribute to genomic instability.
