Removed section[edit]

I removed the following section and heading, recently added to the end of this page. It is no doubt something quite relevant here, but I cannot make sense of it, even after following the link to heterochromatin and the outside page there.

==Position-effect variegation==
The heritable suppression of genes that results from their abnormal translocation to a position close to heterochromatin.

used in medicine in describing some tumors. please add link if this already exists somewhere else. Tkjazzer (talk) 04:28, 3 February 2008 (UTC)


It is misleading to describe them as having different genetic makeup. Typically the genes are the same, but they are expressed differently. The different expression is passed along as cells divide. Sometimes this is due to position-effect variegation, where a gene moves to a more active or repressed region of the genome during cell division. N1ugl (talk) 15:12, 26 June 2012 (UTC)
