Genotypes at the HO locus of S. cerevisiae isolates

Genotype at HO
Origin of isolates Microsatellite profiles HO/HO HO/ho ho/ho
Clinical Polyallelic (diploid) 2 1 4
Monoallelic 1 0 0
Nonclinical Polyallelic (diploid) 4 0 1
Monoallelic 23 0 0

Genotypes at the HO locus of 36 clinical and nonclinical Saccharomyces cerevisiae isolates with either exclusively monoallelic profiles at 12 examined microsatellite loci or polyallelic profiles suggestive of a diploid state of the isolates; the genotype at the HO locus was determined by analysing the sporulation proficiency of the isolates' segregants; sporulation proficient segregants were considered HO (homothallic) and sporulation deficient segregants were considered ho (heterothallic); isolates that exhibited 2:2 segregation of HO:ho were considered heterozygous at HO, and sporulation deficient segregants were tested for heterothallism and haploidy by mating type tests.
