Based on CGH microarrays, we determined whether the spore cultures were disomic (indicated by 2 in the table) or monosomic (indicated by 1) for each homolog. Boldface indicates a tetrad in which one sister spore was monosomic, although the other sister was disomic, indicating a chromosome loss event in the monosomic spore.
a
In these spores, there was a possible chromosome gain. The extra chromosomes were not counted in the averages at the bottom of the table.
b
Average number of individual homologs per tetrad.
