Postmeiotic segregation in Saccharomyces

Summary

Diploid monohybrids of adenine 8 alleles were constructed to permit visual detection of meiotic gene conversion. In addition to the 3+:1 m and 1+:3 m tetrads routinely encountered, aberrant segregations comparable to the 5+:3 m and 3+:5 m patterns detected in octad ascomycetes were observed. These latter types are tetrads bearing ascospores which give rise to sectored ascosporal colonies.
