Self-fertilization (selfing) favours reproductive success when mate availability is low, but renders populations more vulnerable to environmental change by reducing genetic variability. A mixed-breeding strategy (alternating selfing and outcrossing) may allow species to balance these needs, but requires a system for regulating sexual identity. We explored the role of DNA methylation as a regula...

Sex differences in the brain may be the basis not only for sex differences in reproduction, gender identity (the feeling of being male or female), and sexual orientation (heterosexuality vs homosexuality), but also for the sex difference in prevalence of psychiatric and neurological diseases ( Swaab and Hofman, 1995 ). In this brief article we discuss a few examples of structural and functional...

this study reviews the formations of the family in shahnameh; distribution of power in it; and its identity. therefore, we study the theoretical background related to the subject of the research, theories related to the topic of cultural theories of malinowski, radcliffe brown, ario and shlensky, ronard and proposed research and theoretical framework of the research were written according to th...

In order to learn more about the role of sex chromosome-dependent gene products in gonadogenesis, changes in protein patterns were studied during gonadal development. Two-dimensional gel electrophoresis analysis revealed specific proteins in both sexes at all developmental stages. Evidently the gonads are not indifferent by biochemical criteria at any developmental stage and express several spe...

INTRODUCTION Determination of sex from an unknown human bone is an important role in forensic and anthropology field. The mandible is the largest and hardest facial bone, that commonly resist post mortem damage and forms an important source of information about sexual dimorphism. AIM To determine the sex of unknown human adult mandible using metrical parameters. MATERIAL AND METHODS A rando...

Unlike sex determination in the soma, which is an autonomous process, sex determination in the germline of Drosophila has both inductive and autonomous components. In this paper, we examined how sexual identity is selected and maintained in the Drosophila germline. We show that female-specific expression of genes in the germline is dependent on a somatic signaling pathway. This signaling pathwa...

Three studies (N=329) using U.S. community samples examined the relative contributions of self-reported “sex,” gender identity, and actual number of sexual partners to the question how many sexual partners individuals desire over the lifetime. In Study 1, the more “feminine” a participant identified, not self-reported sex, was significantly related to the desired number of sexual partners. Stud...

Background: Professional ethics has been considered by many Iranian organizations in the last decade. Because the roots of many behaviors and activities of managers and professors should be sought in ethics and moral values. Accordingly, the purpose of this study was to investigate the relationship between professional ethics and individual accountability of professors with the mediating role o...
