Lampbrush chromosome

Lampbrush chromosomes are not the same as polytene chromosomes. Although it is not stated in the article, I think they shouldn't be mentioned here. It is confusing and unnecessary. A good place for it would be "See also".--Miguelferig (talk) 18:09, 24 April 2012 (UTC)[reply]

see scale bar in figure below

I'd love to do that, but I can't find a figure with scale bars. 134.95.7.245 (talk) 10:10, 16 January 2014 (UTC)[reply]

Bar-phenotype/Barr body?

User Chhandama has mistakenly linked the Bar phenotype to the page on Barr bodies. The prior is a phenotype derived from a mutation on the D.melanogaster X chromosome, the latter a phenomena of X-inactivation in many animals.

Also note that Drosophila has a different means of dosage compensation for sex chromosomes: instead of inactivating one copy of the X chromosome in females, males overexpress genes on their sole X chromosome.

For future edits, please ensure your information is correct. This is an embarrassing mistake.
