title: Meiotic alterations in CAG repeat tracts.
abstract: We have investigated meiotic changes in CAG repeat tracts embedded in a yeast chromosome. Repeat tracts undergo either conversion events between homologs or expansion and contraction events that appear to be confined to a single chromatid. We did not find evidence for conversion of tract interruptions or excess exchange of flanking markers.
