Predictive Accuracy of Mandibular Ramus Flexure as a Morphologic Indicator of Sex Dimorphism in Jordanians
Provedor de dados: 77
Autores: Badran,D. H; Othman,D. A; Thnaibat,H. W; Amin,W. M.
The present study investigated the validity of mandibular ramus flexure in sex differentiation among young Jordanian adults using Orthopantomographic images in a double blind study. A normative sample comprised of 419 images was selected, of which 126 belonged to male patients and 293 images to females. The exclusion criteria used in the selection involved excluding images that showed marked loss of mandibular molars, over erupted, tilted, anomalous molars and teeth or mandibles associated with pathology. Each image was examined for the presence of a flexure on the posterior margin of the ramus at the occlusal plane. The posterior margin of the ramus was carefully traced graphically and the occlusal plane level was delineated as guided by the height of...

Growing knowledge and understanding of dichromatism and sex reversal in Labridae
Provedor de dados: 16
Autores: Roede, Machteld J.
A brief survey is given of current literature in comparison with former studies. Since the 18th century phenotypic diversity of Labridae is a matter of argument. At first in dribs and drabs, yet last decades at a rapid rate, dichromatic adult morphs are synonymized. There are few monochromatic species. Wrasses are protogynous hermaphrodites. Most species are described as monandric, but a minority (of slightly or extremely dichromatic) species is diandric, with both primary and secondary males. Terminal males reproduce with single females, but initial phase males spawn in aggregations. Some species are haremic, and large males are permanently or temporarily territorial. Last decades insight in the various social factors has greatly increased, resulting in...
