[edit] Name

Should the name of this article be heterogeneity? I'm not sure what the general guidelines are, but it seems more natural that the name of the article should be a noun when possible. Threepounds 07:21, 26 November 2005 (UTC)

Yes. It should certainly match the article on homogeneity.--RichardVeryard 23:40, 8 August 2006 (UTC)

[edit] Disambiguation

As with the article on homogeneity, there are lots of pages that link here, referring to various notions of heterogeneity that are not explicitly identified on this page. Many of them refer to people - cultural, demographic, ethnic heterogeneity - and come from such diverse disciplines as sociology, anthropology, politics and marketing. We probably need a series of articles to cover these various notions - but how many?--RichardVeryard 23:40, 8 August 2006 (UTC)

[edit] Overlap of material with homogeneity

Suppose we decided we needed some material on homogeneity/heterogeneity in culture. Would we want an article on Cultural homogeneity and also an article on Cultural heterogeneity? I think it would generally be easier to write (and more useful to read) a single article covering both.--RichardVeryard 23:40, 8 August 2006 (UTC)

Can heterogeneous mixtures be seperated into simpler substances by purely physical means? —Preceding unsigned comment added by 75.189.140.218 (talk) 20:16, 31 October 2007 (UTC)

[edit] Caution: Incorrect defenitions of Genetic Meanings!

If a number of different mutations occurring the same locus of a gene produce same disorder, such disorder is said to manifest allelic heterogeneity

Allelic heterogeneity of RET gene causes clinic heterogeneity: (a) Hirschprung disease (b) multiple endocrine neoplasia are caused by mutation in the same RET gene but are strikingly different phenotypes!

This doesn't exclude that allelic heterogeneity can cause the same disorder. 1300 alleles of cystic fibrosis are known.

Thus, allelic heterogeneity leads to two states: 1. the same disease with not great variation (as CF) 2. strikingly different phenotypes as with RET gene. State (2) is called clinic heterogeneity. That is clinic heterogeinity is result of allelic heterogeneinty.

See Genetics In Medicine for reference.
