| 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. (05 Mar 2000) |
|---|
| 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) |

Compare single-gene disorders. (05 Mar 2000) |
| diseases, polygenic | Genetic disorders that are caused by the combined action of more than one gene.

Because such disorders depend on the simultaneous presence of several genes, they are not inherited as simply as single-gene diseases. (12 Dec 1998) |
| alternative inheritance | Galton's term for an assumed form in which all the characters are derived from one parent. (05 Mar 2000) |
| blending inheritance | Galton's term for inheritance in which no component is conspicuous or obtrusive. (05 Mar 2000) |
| galtonian 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. (05 Mar 2000) |
| recessive inheritance | dominance of traits |
| maternal inheritance | Inheritance through the maternal cell line, for example through the oocyte and eggs. Mitochondrial genes are maternally inherited and various other nonMendelian forms of inheritance may also appear as maternal inheritance. (18 Nov 1997) |
| Mendelian inheritance | <genetics> Inheritance of characters according to the classical laws formulated by Gregor Mendel, which give the classic ratios of segregation in the F2 generation. In sexually reproducing organisms, any process of heredity explicable in terms of chromosomal segregation, independent assortment and homologous exchange. (18 Nov 1997) |
| Mendelian Inheritance in Man | A standard, comprehensive, perpetually updated reference source for traits in humans that have been shown to be mendelian or that are thought on reasonable grounds to be so. Each entry has a six-digit catalog number. Those securely established (by molecular biology or by extensive clinical studies) are marked with an asterisk. (05 Mar 2000) |
| mitochondrial inheritance | The inheritance of a trait encoded in the mitochondrial genome. Because of the oddities of mitochondria, mitochondrial inheritance does not obey the classic rules of genetics. Persons with a mitochondrial disease may be male or female but they are always related in the maternal line and no male with the disease can transmit it to his children. (12 Dec 1998) |
| codominant inheritance | Inheritance in which two alleles are individually expressed in the presence of each other; there may be other alleles available at the locus that may or may not exhibit codominance. (05 Mar 2000) |
| collateral inheritance | The appearance of characters in collateral members of a family group, as when an uncle and a niece show the same character inherited from a common ancestor; in recessive characters it may appear irregularly, in contrast to dominant characters transmitted directly from one generation to the next. (05 Mar 2000) |
| polygenic inheritance |
多基因遺傳病, The transmission of a phenotypic trait whose expression depends on the additive effect of a number of genes.

| polygenic inheritance |
A trait is caused by two or more genes working together. In Aussies, the natural bobtail is polygenic. There are probably several muliple genes involved in determining exact iris color. The inheritance of a trait dependent on multiple genes is harder to predict than one based on a simple dominant/recessive relationship of alleles of the same gene.
