The Sex Ratios of Monozygotic and Dizygotic Twins

Twin Research and Human Genetics, 2010
AbstractFellman and Eriksson (2010) cited my suggestion that the sex ratio (proportion male) of monozygotic (MZ) twins is lower than that of dizygotic (DZ) twins (James 1975). Here I offer elaborations on and potential explanations for this.

Congenital diaphragmatic hernia in dizygotic twins

Journal of Pediatric Surgery Case Reports, 2015
Congenital diaphragmatic hernia (CDH) is sometimes seen in siblings but is rarely seen in twins, and five survived cases of CDH in monozygotic or dizygotic twins have been reported in the English literature. Here we report a sixth survived case of CDH in

Traces of embryogenesis are the same in monozygotic and dizygotic twins: not compatible with double ovulation

Human Reproduction, 2009
Common knowledge of over a century has it that monozygotic and dizygotic twinning events occur by unrelated mechanisms: monozygotic twinning ‘splits’ embryos, producing anomalously re-arranged embryogenic asymmetries; dizygotic twinning begins with ...

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.

Myotonia Congenita in Dizygotic Twins

European Neurology, 2008
A pair of dizygotic twins suffering from myotonia congenita born in Great Britain, is described. The twins were subjected to genetic, biochemical and electromyographic studies as were 5 relations in three generations. Spina bifida occulta was found in both popositi and is regarded as coincidental.

Duodenal atresia in dizygotic twins

Journal of Pediatric Surgery, 1997
The authors report duodenal atresia occurring in both members of dizygotic twins who showed no signs of Down's syndrome, and both had normal chromosomal constitutions. They both had the two unlinked end type of atresia in the second portion of the duodenum, and direct end-to-end duodenoduodenostomy was carried out.

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 ...
