摘要：

Triploidy may arise from either digynic or diandric fertilizations. Errors in the second meiotic division account for most digynic triploidy while most studies have found that similar to2/3 of diandric triploids arise as the result of dispermy and 1/3 as the result of meiotic errors giving rise to diploid sperm. Using molecular markers very close to the centromere, all 14 cases of diandric triploidy were shown to be the result of dispermy with no evidence to support a meiotic error as the origin of diandric triploids.
