MONOZYGOTIC AND DIZYGOTIC TWIN DIAGNOSIS

Annals of Human Genetics, 1955
SummaryA method of estimating the probability of dizygotic and monozygotic twin pairs is described. Parent‐child and sib‐sib frequency tables for the ABO, MNS and Rhesus blood‐group systems and formulae for obtaining these tables for the P, Lutheran, Kell, Duffy, Kidd and non‐secretor (or Lewis) systems are given.Tables of the distribution of ...

Dizygotic twins with myelomeningocele

The Indian Journal of Pediatrics, 2003
Among the neural tube defects incidence of spinabifida and myelomeningocele is less in twins compared to singletons. This article reports a case of dizygotic twins with myelomeningocele, a rare occurrence. Possible association of twining and neural tube defects and its impact on genetic counseling in such cases has been discussed.

Coital rates and dizygotic twinning

Journal of Biosocial Science, 1972
There is some evidence, mostly of an epidemiological nature, that coital rates may be positively associated with dizygotic twinning. It is suggested that this link is causal, in which case an explanation becomes available for some curious—and hitherto unexplained—features of dizygotic twinning rates by maternal age and legitimacy.
