    20 cases were maternal and 5 paternal in origin. Among the digynic cases 10 were inferred to be due to error at meiosis I and the other 10 due to errors at meiosis II. All the diandric cases were due to dispermy.

    Three different mechanisms for mosaic diploid/triploid are proposed: i) chimaerism with karyotypes from two separate zygotes developing into a single individual, ii) delayed digyny, by incoproration of a pronucleus from a second polar body into one embryonic blastomere, and iii) delayed dispermy by incorporation of a second sperm pronucleus into one embryonic blastomere.

    Robinson et al found that the etiology of trisomy is predominantly a result of meiotic errors related to increased maternal age.

They further suggest that virtually all triploidy is a consequence of an error in the ovum either a division error leading to digyny or an abnormality of the ovum that fails to block fertilization by more than one sperm.

    91 cases of spontaneous abortions were examined.
    These authors found that paternally-derived cases predominate among "typical"spontaneous abortions, whereas maternally-derived cases are associated with either early embryonic demise or with relatively late demise involving a well-formed fetus. They also found that the majority of cases were diandric in origin because of dispermy.
