Talk:Variegation

Removed section
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)

chimeras?
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)

A brief word of thanks
I was out in my garden this morning, which contains some variegated plants. Out of nowhere a question popped into my head - "Hang on! The green is from chlorophyll, so aren't these leaves less efficient? By the rules of natural selection they shouldn't exist in such abundance should they?

So I came to Wikipedia, and near the top of the article...

"As these plants have some of their tissue unable to carry out photosynthesis, the plant will be weaker than the plain green plant. They should generally be expected to die out in nature and their only real source of survival is through cultivation."

What an amazing resource this is. Ride the Hurricane (talk) 09:46, 28 February 2015 (UTC)

Colour vs. color?
Wikipedia was created in the U.S., and this is the U.S. version.

So, why does this article us the British spelling, "colour"? If this were a British website, I'd insist that British spelling be used. So, why the inconsistency here?

An answer that uses logic, as opposed to cultural chauvinism, would be appreciated. — Preceding unsigned comment added by 24.5.235.228 (talk) 19:35, 20 April 2019 (UTC)

Insect leaf miner
"leaf variegation may appear to an insect leaf miner that the leaf is already infested" Is that proper English? It seems as if insect is just like an adjective here. Am I reading that sentence wrong? Samorost1 (talk) 06:37, 26 April 2021 (UTC)


 * Maybe rephrasing
 * "In this, leaf variegation may appear to a leaf mining insect that the leaf is already infested, and this may reduce parasitization of the leaf by leaf miners."
 * to
 * "In this, leaf discoloration can give a leaf mining insect the impression that the leaf is already infested, possibly reducing the parasitization of the leaf by leaf miners.
 * would help? The original sentence seems to be proper English, but is hard to read. 92.50.117.229 (talk) 10:03, 2 June 2023 (UTC)
