Sex Determining Mechanisms in Vertebrates
نویسنده
چکیده
7. 1. Summary Vertebrates have various sex determining mechanisms. These have been broadly classified as either genotypic sex determination (GSD) or environmental sex determination (ESD). This terminology, however, may obscure the fact that mixtures between genotypic and environmental sex determination exist, or that genotypic and environmental sex determination may, in fact, be the extremes of a continuum. Sex ratio evolution plays an important role in the evolution of sex determining mechanisms.

Sexual reproduction is one of the most highly conserved processes in evolution. However, the genetic and cellular mechanisms making the decision of whether the undifferentiated gonad of animal embryos develops either towards male or female are manifold and quite diverse. In vertebrates, sex-determining mechanisms range from environmental to simple or complex genetic mechanisms and different mec...
متن کاملThe Variety of Vertebrate Mechanisms of Sex Determination
The review deals with features of sex determination in vertebrates. The mechanisms of sex determination are compared between fishes, amphibians, reptilians, birds, and mammals. We focus on structural and functional differences in the role of sex-determining genes in different vertebrates. Special attention is paid to the role of estrogens in sex determination in nonmammalian vertebrates.
متن کاملMolecular mechanisms involved in mammalian primary sex determination.
Sex determination refers to the developmental decision that directs the bipotential genital ridge to develop as a testis or an ovary. Genetic studies on mice and humans have led to crucial advances in understanding the molecular fundamentals of sex determination and the mutually antagonistic signaling pathway. In this review, we summarize the current molecular mechanisms of sex determination by...

The involvement of the Y chromosome in sex determination was determined by the development and the application of techniques for karyotyping the mammalian chromosome in 1960s. There were many reports on the particular region of the Y chromosome, such as histocompatibility (H-Y) antigen, bandit krait minor satellite (Bkm) the zinc finger Y gene (ZFY) and the sex-determining region of the Y chrom...

Sex determination, the step at which differentiation of males and females is initiated in the embryo, is of central importance to the propagation of species. There is a remarkable diversity of mechanisms by which sex determination is accomplished. In general these mechanisms fall into two categories: Genetic Sex Determination (GSD), which depends on genetic differences between the sexes, and En...
