Dispermy is considered to be the most common cause of triploidy.
Thus, the mechanism causing triploidy was more likely to have been either dispermy or a non-disjunction event in meiosis 1 and very unlikely to have been due to an event in meiosis 2.
Allele patterns for CHMs were consistent with monospermy in 25 cases (81%) and dispermy in 6 cases (19%) (Figure 1).
