I did a few months ago at Ancestry dot com. Recording a family tree is not always accurate due to incomplete records or deliberately overlooking illegitimate births, etc. The DNA test goes back thousands of years, which makes the results interesting. Without going into all the results, I'm either 1/16 or 1/8 American Indian, but the DNA results say zero...either the DNA test is suspect or more likely, my family documentation is wrong/lied.
I have not. 23andme.com was founded by Anne Wojcicki the wife Sergy Brin one of the Google founders. She has a BS in Biology. This is actually better since it provides Genetic testing for over 240 ailments, drug reactions, etc. At the least read the web site to get more info. The ancestry part is interesting, it actually tells you what famous people you are related to. Tells you about distant famous relatives for example Benjamin Franklin or a King or Italian Count etc. The cost is $99. 23andMe - Genetic Testing for Health, Disease & Ancestry; DNA Test
What my family records say: Irish Scottish English? German American Indian What the DNA from Ancestry dot com says: 87% British (Many people from Ireland and Germany share this DNA - apparently the case with me. Also France, Belgium, Netherlands) I'm more British than their Royal Family. (Most royal families have diverse ancestry) 7% Spanish. This is from thousand of years ago when they immigrated to Britain - common with a lot of British. So it's not Hispanic. 3% Eastern European. 1% Italian and/or Greek. < 1% less North African < 1% Western Asian (area east of Israel to Black Sea/former Soviet states)
There are a large and growing number of companies doing this What I don't know is whether their results get combined in any way. It could be very interesting, even though much information would be kept anonymous. Should you want to be overwhelmed by the technology, see: Genealogical DNA test - Wikipedia, the free encyclopedia From which I will only excerpt Y-chromosome 'junk in the trunk' because it sounds funny.
I recall reading someone sent the same DNA to ancestors dot com and got different results. Got to wonder how accurate it is? Evidently there are a few different types of tests and that may be why
I'm 100% human. Although, I've heard we share 97% of our DNA with chimpanzees, so I'm not entirely certain.
I think the medical testing is interesting. If you are pre deposition to a certain type of cancer you may want to test for it yearly to catch it soon
Easy to explain Bra... I think I recall reading something about that too... but as I remember, it was siblings... . . . . . . . . . . . . . . . . . . . . . . . . . . . . . The milkman cumith.
By DNA phylogenies, animals, plants and fungi had a 3-way split at about the same time*. So you and the banana and the mushroom have about the same commonality. It is less surprising if you realize that we have very many essential metabolic processes in common. Those are simply unavailable for evolutionary tweaking. The critters most 'different' from you may be hot-springs bacteria that use various metals for electron acceptors (whatever that means ) All of this fluffs the issue of viruses, that are or are not alive depending on your point of view. At the same time their DNA/RNA shows up everywhere because it is so 'injectable'. A rather old Siberian (human) bone was recently sequenced (new in Nature journal). Interesting that they had to use somebody from India to do the work so it would be easier to subtract out his 'contamination'. The amplification techniques are absurdly sensitive. * 600 million years ago, give or take
Oh, and Fred Sanger, the father of DNA sequencing, just died at age 95. Perhaps somebody 'kept a copy' of him.
