Abstract In evolutionary biology, sexual mating plays a pivotal role in facilitating the combination of beneficial alleles among individuals. Cross-species data suggest that organisms selectively choose mating partners based on factors such as genetic distance and partner fitness. Understanding the determinants of mate selection is crucial for unraveling the impact of sex on evolution.

Abstract Quantitative genetics requires large datasets of diverse phenotyped-genotyped strains from the same species. A special need is for such archived biological material and computerized data in sexually reproducing individuals from a species. Here we leverage sexual mating among close to 100 diverse natural isolates of the yeast S. cerevisiae that form about 4,000 offspring combinations in several ecologically relevant growth conditions.
