Referring to having a gene for a trait is no longer the scientifically accepted usage. In most cases, all people would have a gene for the trait in question, but certain people will have a specific allele of that gene, which results in the trait variant. Further, genes code for proteins, which might result in identifiable traits, but it is the gene, not the trait, which is inherited.

No footnotes date November 2011 Gene silencing is a general term describing epigenetic processes of gene regulation . The term gene silencing is generally used to describe the switching off of a gene by a mechanism other than genetic modification . That is, a gene which would be expressed turned on under normal circumstances is switched off by machinery in the cell. Gene s are regulated at either the Transcription ... gene silencing is the result of histone modifications, creating an environment of heterochromatin around a gene that makes it inaccessible to transcriptional machinery RNA polymerase , transcription factors , etc. . Post transcriptional gene silencing is the result of Messenger RNA mRNA of a particular gene being destroyed or blocked. The destruction of the mRNA prevents translation to form an active gene product in most cases, a protein . A common mechanism of post transcriptional gene silencing is RNAi . Both transcriptional and post transcriptional gene silencing are used to regulate endogenous genes. Mechanisms of gene silencing also protect the organism s genome from transposon s and virus es. Gene silencing thus may be part of an ancient immune system protecting from such infectious ... fungus Neurospora crassa .

Unreferenced stub auto yes date December 2009 A candidate gene is a gene , located in a chromosome region suspected of being involved in the expression of a trait such as a disease, whose protein product suggests that it could be the gene in question. A candidate gene can also be identified by association with the phenotype and by linkage analysis to a region of the genome. A popular way to identify candidate genes is by microarray , this allows the researcher to analyse the expression levels of specific genes in a case control study, therefore if a gene is dysregulated in a disease it may be identified by microarray. However microarray has its weaknesses as it identifies all expression in the cell and could be reporting the expression of a gene which is affected by the disease rather than the cause.

Discovered in the Caenorhabditis elegans C. elegans genome. Ced9 is the gene that codes for a protein that inhibits represses apoptosis . The human version of the gene is called Bcl 2 . The protein prevents the release of cytochrome c in the membrane of mitochondria Robert Horvitz initial work with C. elegans isolated 3 different mutants with gene alterations that prevented programmed cell death . He identified the mutant genes as Ced3, Ced4, and Ced9 genes each of the genes could independently cause cell immortality. He concluded that these three genes must act in the same pathway. http www.wormbase.org db genegene?name WBGene00000423 class Gene The Cell A Molecular Approach, Fifth Edition, by Geoffrey M.
