Sequencing data from 78 heterozygous S. cerevisiae mutation accumulation lines with different ploidies (2n, 3n, 4n), derived from isolates from various geographical and ecological origins to study patterns of loss of heterozygosity.. Sequencing data from 78 heterozygous S. cerevisiae mutation accumulation lines with different ploidies (2n, 3n, 4n), derived from isolates from various geographical and ecological origins.

We propagated and sequenced 78 heterozygous S. cerevisiae mutation accumulation lines with different ploidies (2n, 3n, 4n), derived from isolates from various geographical and ecological origins. All S. cerevisiae lines were sequenced with Illumina technology.
