Preimplantation genetic diagnosis (PGD) was • fi rst applied in 1988 using a polymerase chain reaction (PCR) protocol to amplify a sequence on the Y chromosome for embryo sexing for patients carrying X-linked disease. Patients have to go through in vitro • fertilization (IVF) so that their embryos may be generated in vitro. Cells are removed from oocytes or embryos and used for the genetic diag...

The bullfinch Loxigilla barbadensis is an endemic passerine on the Caribbean island of Barbados that has only recently been taxonomically split from the Lesser Antillean bullfinch L. noctis. The trait that most clearly distinguishes L. barbadensis from L. noctis is the absence in the male of sexually dimorphic coloration of the body and throat feathers, with L. barbadensis males and females sha...

The eighth report of the European Society of Human Reproduction and Embryology PGD Consortium is presented documenting cycles collected for the calendar year 2005 and follow-up of the pregnancies and babies born until October 2006 which resulted from these cycles. For the first time, the delivery rates for each indication are presented and also the pregnancy rates for each centre are reported a...

Human skull is shown to exhibit numerous sexually dimorphic traits. Estimation of sex is a challenging task especially when a part of skull is brought for medicolegal investigation. The present research was planned to evaluate the sexing potential of the dimensions of foramen magnum in forensic identification by craniometric analysis. Length and breadth of the foramen magnum was measured using ...

Schistosoma mansoni is a digenean parasite known for its importance as a human pathogen. Compared with the other genera belonging to the digenean families, the Schistosoma genus is characterized by having acquired gonochorism from hermaphroditic ancestors [1]. Sex is genetically determined in the egg [2] and female schistosome is heterogametic (ZW) such as lepidoptera, reptiles and birds. A mar...

The accuracy of the sex determination of cremated human remains is one of the vital parameters for archaeologists and skeletal anthropologists dealing with cremations. Few studies have so far aimed at testing it. In the present paper, the accuracy of the sexing techniques was assessed by paralleling biological sex (identified morphologically) to gender (presumed on the basis of the grave goods ...
