| sex hormone-binding globulin | A glycoprotein migrating as a beta-globulin. Its molecular weight, 52,000 or 95,000-115,000, indicates that it exists as a dimer. The protein binds testosterone, dihydrotestosterone, and estradiol in the plasma. Changes in its concentration significantly affect the ratio of unbound (biologically active) testosterone to estradiol in plasma. (12 Dec 1998) |
|---|---|
| sex hormones | Hormones having oestrogenic (female sex hormones) or androgenic (male sex hormones) activity. (12 Dec 1998) |
| sex-influenced | Denoting a class of genetic disorders in which the same genotype has differing manifestations in the two sexes; the variation may be rational (e.g., breast cancer occurs less frequently in males) or have only empirical support (e.g., pattern baldness behaves as a dominant trait in the male and as a recessive trait in the female). See: sex-influenced inheritance. (05 Mar 2000) |
| sex-influenced esterase | <enzyme> Sex hormone-dependent enzyme; liver enzyme may be a precursor of sex-influenced esterase Registry number: EC 3.1.1.- Synonym: es-si esterase, liver sex-influenced esterase (26 Jun 1999) |
| sex-influenced inheritance | Inheritance that is autosomal but has a different intensity of xpression in the two sexes, e.g., male pattern baldness. (05 Mar 2000) |
| sex-limited | Occurring in one sex only. See: sex-limited inheritance. (05 Mar 2000) |
| sex-limited inheritance | Inheritance of a trait that can be expressed in one sex only, e.g., testicular feminization. (05 Mar 2000) |
| sex-linked | <genetics> A genetic disorder where the genetic defect is linked to one of the chromosomes that determines sex (x or y). This is usually due to a gene on the unpaired portion of the X chromosome. Recessive X linked alleles are fully expressed in the heterogametic sex because they can have only one copy of the gene. Thus X linked mutant disorders are more common in human males than in females. An example is haemophilia, which is autosomal recessive and linked to the X chromosome, so only males (XY) actually manifest the disease. (06 Oct 1997) |
| sex-linked character | An inherited character determined by a gene on a gonosome. See: gene. (05 Mar 2000) |
| sex-linked inheritance | The pattern of inheritance that may result from a mutant gene located on either the X or Y chromosome. (05 Mar 2000) |
| sex-linked locus | Any locus that in normal karyotypes is borne on a heterosome; commonly but incorrectly applied to an X-linked locus. (05 Mar 2000) |
| sex manuals | Books used for sex education and procedural instruction. (12 Dec 1998) |
| sex maturation | Achievement of full sexual capacity. Applies to animals and humans. (12 Dec 1998) |
| sex offenses | Any violation of established legal or moral codes in respect to sexual behaviour. (12 Dec 1998) |
| sex pili | <cell biology> Fine filamentous projections (pili) on the surface of a bacterium that are important in conjugation. Often seem to be coded for by plasmids that confer conjugative potential on the host, in the case of the f plasmid, the F pili are 8-9nm diameter and several microns long, composed of pilin. Whether the pili merely serve to establish and maintain adhesive contact between the partners in conjugation or whether DNA is actually transferred through the central core of the pilus is still unresolved, although a simple adhesion role is more generally accepted.
