Percentage of diploid and aneuploid individuals in the various crosses. For each cross-type, the percentage of diploid (green), simple aneuploids (light blue), and complex aneuploids (dark blue) are represented. Complex aneuploids represent individuals with partial chromosomes, suggesting the presence of at least two breaks in a single chromosome. The overall percentage of aneuploid individuals is highest in the crosses involving the ta mutant (panel A). In those crosses, extra copies of the bottom arm of chromosome 3 (Chr. 3B) possibly originated from the parental line. Those individuals are discarded in panel B.
