Is it just me or would this get to you too?

I participate on a genealogy dna forum. A member has developed a new DIY calculator. He has also provided a link to a drop down menu where you can choose your forum name and get a map of where your chromosomes are. I inquired whether chromosome 1 was in Poland as the map isn't labelled. The reply from the member

Quote:
- By chromosome, it's not really accurate.
Do not read literally!


So why have that function ,and how are you supposed to take such a thing in a non literal sense ?!

Sounds like a very amateurishly put together forum.

Its not that his reply is offensive. Its that his whole project is too harebrained to be of any value.

We have tens of thousands of "genes" that are packed onto 23 pairs of chromosomes.

The point of DNA geneology is to find the origin of your genes, and not of your entire "chromosomes". (the origins of the merchandise on the 23 aisles of the store, not of the unchanging aisles of the store itself).

As I understand it: if you are say mixed ancestry - you could have genes coming from Poland, and genes coming from Japan, and etc. But your whole chromosome one would not come from the same one place.

I didn't think he was rude or anything. To be frank I'm really into this stuff, but I get thrown by the regular calls not to take any populations, apart from British isles(which I have a paper trail for),which are given literally.
I've done another by chromosome test where for example chromosome 1 was broken down as follows-

"distance%=1.6558"
NL_Groningen,53.2
Sachsen-Anhalt,14.4
IT_Bolzano,12.4
Finnish_Swede,4.2
Tirol,3
Estonia_SW,2.2

etc.


There is some complex methodology behind these DIY autosomal dna tools that is way above my intellectual pay grade. However does 'Complex' always equal 'Sound' ?

I'm confused by this whole thing. I am thinking the same you are. I also find it interesting how Tirol is at a distance of 3 but Bolzano is 12, while Finnish Swede, being least related to either of those, is at 4.2.

My fault for not explaining properly. The Bolzano 12 etc is the % which the chromosome can,supposedly, be attributed to that particular population.
