| polygastric | 1. <anatomy> Having several bellies; applied to muscles which are made up of several bellies separated by short tendons. 2. <zoology> Pertaining to the Polygastrica. Origin: Poly- + gastric: cf. F. Polygastrique. <zoology> One of the Polygastrica. Source: Websters Dictionary (01 Mar 1998) |

| polygastrica | <zoology> The Infusoria. Origin: NL. So called because they were supposed to have several stomachs, or digestive cavities. Source: Websters Dictionary (01 Mar 1998) |
| polygeline | <chemical> A 3.5 per cent colloidal solution containing urea- cross-linked polymerised peptides. It has a molecular weight of approximately 35,000 and is prepared from gelatin and electrolytes. The polymeric solution is used as a plasma expander. Pharmacological action: plasma substitutes. (12 Dec 1998) |
| polygene | One of many genes that contribute to the phenotypic value of a measurable phenotype. (05 Mar 2000) |
| polygenes | Many genes. Eye colour is polygenically controlled. (12 Dec 1998) |
| polygenettic | 1. Having many distinct sources; originating at various places or times. 2. <biology> Of or pertaining to polygenesis; polyphyletic. <geology> Polygenetic mountain range, one which is composite, or consists of two or more monogenetic ranges, each having had its own history of development.

| polygenic | <genetics> Pertaining to the combined action of alleles of more than one gene. Height is an example of a polygenic trait, as are predispositions to different types of heart disease. Origin: Gr. Gennan = to produce (14 Nov 1997) |
| polygenic diseases | Genetic disorders that are caused by the combined action of more than one gene. Examples of polygenic conditions include hypertension, coronary heart disease, diabetes, and peptic ulcers. Because such disorders depend on the simultaneous presence of several genes, they are not inherited as simply as single-gene diseases. (12 Dec 1998) |
| polygenic disorder | <genetics> Genetic disorders resulting from the combined action of alleles of more thanone gene (for example, heart disease, diabetes, and some cancers). Although such disorders are inherited, they depend on the simultaneous presence of several alleles, thus the hereditary patterns are usually more complex than those of single-gene disorders. (14 Oct 1997) |

Although such disorders are inherited, they depend on the simultaneous presence of several alleles, thus the hereditary patterns are usually more complex than those of single- gene disorders. Compare single-gene disorders. (05 Mar 2000) |
| polygenic inheritance | Inheritance in which a measurable phenotype is generated by many loci, the contributions of which are statistically independent, additive, and of about equal value. (The latter are in accordance with the classical central limit therein and justify the use of the multivariate normal distribution in galtonian genetics). Synonym: polygenic inheritance.

| polygenism | <biology> The doctrine that animals of the same species have sprung from more than one original pair. Origin: Cf. F. Polygenisme. Source: Websters Dictionary (01 Mar 1998) |
| polygenist | <biology> One who maintains that animals of the same species have sprung from more than one original pair; opposed to monogenist. Source: Websters Dictionary (01 Mar 1998) |
| polygeny | <biology> The theory that living organisms originate in cells or embryos of different kinds, instead of coming from a single cell; opposed to monogenesis. Origin: Poly- + genesis, or root of Gr. To be born. Source: Websters Dictionary (01 Mar 1998) |
| polyglactin 910 | <chemical> 2-hydroxy-propanoic acid polymer with polymerised hydroxyacetic acid, which forms 3,6-dimethyl-1,4-dioxane-dione polymer with 1,4-dioxane-2,5-dione copolymer with molecular weight about 80,000 daltons. Synthetic, absorbable surgical suture material and mesh fabric; used especially in ophthalmic surgery. Chemical name: Propanoic acid, 2-hydroxy-, polymer with hydroxyacetic acid (12 Dec 1998) |
