  1. The percentage of strains containing specific introns is provided for S. cerevisiae strains and related Saccharomyces species. The number of strains within each population is provided (n). When n = 1, intron presence/absence is indicated as +/−. Introns not known as variable (*) or observed (**) in S. cerevisiae are indicated next to their respective group heading. Insertion sites indicate the base pair in the CDS that precedes the intron insertion site.
