| AROA | autosomal recessive ocular albinism |

| y-linked | A gene on the Y chromosome. A y-linked gene is by necessity passed from father to son. (12 Dec 1998) |
|---|---|
| Y-linked gene | A gene located on a Y chromosome. Synonym: holandric gene. (05 Mar 2000) |
| Y-linked locus | Any (haploid) locus that in normal karyotypes is borne on the Y chromosome. The known content is so far small. (05 Mar 2000) |
| flavin-linked dehydrogenase | <enzyme> A dehydrogenase that requires a riboflavin coenzyme to function properly. (09 Oct 1997) |
| linked | Said of two genetic loci that exhibit genetic linkage. (05 Mar 2000) |
| linked gene | <genetics> Genes and / or markers that are so closely associated on the chromosome that they are inherited together in 80% or more of cases. (14 Oct 1997) |
| 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) |
| 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.
