Note on the origin of triploidy in maize

Journal of Genetics Aims and scope Submit manuscript

Summary

Triploid individuals in maize occur through the fertilization of diploid or unreduced eggs by haploid sperm. The diploid eggs have arisen by complete non-disjunction of the entire chromosome set during meiosis or through non-disjunction during one of the three mitotic divisions of the female gametophyte. In either of these eventualities, however, the female gamete carried the diploid number of chromosomes.

Triploidy in maize is here shown to have arisen when the diploid number of chromosomes was contributed by the male parent.
