Talk:Autosome
From Wikipedia, the free encyclopedia
An autosome is an ordinary paired chromosome that is the same in all genders of a species.
An autosomal dominant gene is one on an autosome and is always expressed, even if a single copy exists. The chance is 1:2 for passing this gene to offspring.
Surely the second sentence above is incorrect? Unless something funny happens during recombination, the author has got phenotypes mixed up with genotypes - if the parent in question is heterozygous then there is a 50% chance the gene passed on from that parent is passed to the offspring.
You're right--and I think the last two sentences should be deleted. It looks like it's giving an example of how one would use the word "autosomal," so the second and third sentences, be they correct or not (and the second is not correct) are irrelevant. --ClarkFreifeld 21:45, 19 January 2006 (UTC)
[edit] Gonosome?
Scientific literature usually refers to sex chromosomes as allosomes, heteromorphic sex chromosomes, or heterosomes. Online (English language) dictionary definitions of gonosome have nothing to do with chromosomes at all, so I replaced it.

[edit] Autosomal groupings?
Shouldn't there be some information of the different autosomal groups, just as mtDNA and Y & X STRs have different haplogroups? I know there are different markers for autosomes, so I think wikipedia should have at least some information on the different major markers and their associated frequencies within certain populations; just as the haplogroup pages have done for mtDNA and the Y STRs.

- Added CODIS markers and some links that might help with the above endeavor. Nagelfar 23:36, 1 March 2007 (UTC)
