Several previous studies have investigated the gender difference of the fingerprint features. However, regarding to the statistical significance of such differences, inconsistent results have been obtained. To resolve this problem and to develop a method for gender determination, this work proposes and tests three fingertip features for gender determination. Fingerprints were obtained from 115 ...
Two years ago, I attended an international conference on genetic testing in Rennes, France, where one panel was scheduled to discuss privacy and genetic testing. The specific topic was whether family members ought to have access to an individual’s test results. My assumption, an admittedly naïve and ill-informed one, was that no one, including family members, had any right to this information. ...
This article proposes a dynamic model of the intersections between gender, health, and the life course incorporating processes of strategic selection--of roles, relationships, and behavior. Men and women make decisions within a tangled web of multilayered, often contradictory, and frequently outdated institutional contexts of opportunity and constraint. Both their decisions and the institutions...
Nonautonomous inductive signals from the soma and autonomous signals due to a 2X karyotype determine the sex of Drosophila melanogaster germ cells. These two signals have partially overlapping influences on downstream sex determination genes. The upstream OVO-B transcription factor is required for the viability of 2X germ cells, regardless of sexual identity, and for female germline sexual iden...
AIMS The elasticity of the internal jugular vein (IJV) is a major determinant of cerebral venous drainage and right atrium venous return. However, the level of genetic determination of IJV dimensions, compliance and distensibility has not been studied yet. METHODS 170 adult Caucasian twins (43 monozygotic [MZ] and 42 dizygotic [DZ] pairs) were involved from the Italian twin registry. Anteropo...
Male and female sexes have evolved repeatedly in eukaryotes but the origins of dimorphic sexes and their relationship to mating types in unicellular species are not understood. Volvocine algae include isogamous species such as Chlamydomonas reinhardtii, with two equal-sized mating types, and oogamous multicellular species such as Volvox carteri with sperm-producing males and egg-producing femal...
