What is 23andMe?
Company Link
“Our goal is to connect you to the 23 paired volumes of your own genetic blueprint (plus your mitochondrial DNA), bringing you personal insight into ancestry, genealogy, and inherited traits. By connecting you to others, we can also help put your genome into the larger context of human commonality and diversity.”
It seems as though the company plans on indexing users’ DNA in order to pull up findings that would provide users with information on potential disease states as well as inherited traits.
Services
Customers will send their saliva or cheek swab for DNA sampling, which will be sent to Illumina for genotyping. According
to Venturebeat, Illumina’s microbead-based scanning technology will give customers a rough approximation of what their genome may look like by dectecting DNA variations i.e. single nucleotide polymorphisms (SNPs). The method is cheaper and faster than reading the entire genome. 23andMe will then put the information up on a password protected website where users may analyze their genome.
According to Portfolio, 23andMe is considering to incorporate a social networking element where users may link their personalized pages to those who share their DNA. Think of it as adding a friend in Facebook, but in this case you’re adding a Genetic Associate

Revenue Strategy
23andMe has not specified an amount that they plan on charging but competitors are considering charging $2,000 and upward per user (Portfolio)

Evaluation
23andMe is an interesting concept - the ability to map your genome and have your genes indexed. However, there are questions and issues that I have:
- Would people be willing to send in their saliva or cheek swab to 23andMe?
- Would 23andMe be liable for the emotional distress caused by the information revealed to the patient of his genome?
- Security – who is responsible if the information is leaked to insurance companies?
Although much of the debate over gene testing has been over the potential abuse by insurance companies, employers, or the government, the potential emotional distress caused to the patient from the testing is just as important. Any sort of gene testing would track heredity conditions that may bring devastating news to the patient’s family. Patients need to decide how much they want to know and whether they want to tell their family. Who is responsible for the emotional distress? Will patients get to choose and pick how much they want to know about themselves?
Secondly, there is the issue of cost. If the cost of testing is going to be in the thousands of dollars, how will patients pay for this? Any patient with a history of cystic fibrosis or breast cancer would not feel comfortable having their insurance company pay for their genetic testing. What about healthy patients? Would they want to have insurance companies pay for their genetic testing and if so, would insurance companies hold the right to inspect the patient’s genetic information? And after the insurance companies find out about the patient’s genome, do they have the right to increase the patient’s insurance premium?
There’s a lot of ethical and moral questions that 23andMe will have to address. However, we can argue about morality and ethics all we want, but let us not shut the door to discovery.

KHOI
So why the name 23 and Me? This is basic high school biology. We have 23 pairs of chromosomes. The key word there being “pairs” - one set from our mom and one set from our dad.
So why did they choose the number 23 and not 46? If you were scanning someone’s DNA, wouldn’t it make sense to suggest that you scan the whole thing and not just half of it?

Hi Khoi,
I am an Biotech student and I can answer your question..
your question is we have 23 ( 1 set ) from our father and 23 ( 2nd set) from our mother. so why you call as 23 and not as 46.
my answer: however eventhough we get 23 set from father and other 23 from our mother we have its MODIFIED FORM of chromosomes in our body.
I mean not exactly 100% resemblence of our parents. Our chromosomes will get changed by means of a process called “CROSSING OVER” and produce new set of chromosomes in our body.
Tats why we dont exactly resemble the same as our parents . Its called Variation . Some would have said your eyes look like your mothers and your nose like your fathers. This is due to Heredity.
Now coming to your question.
The answer is in reference to mendels law.
take for example his pea plant experiment.
chromosome 1: T ( fathers) chromosome 2: T ( mothers)
where T is factor for Tallness( height of yours)
here TT see both are similar. so we can represent any one gene.
Now again
chromosome 1: T (fathers) chromosome 2 : t ( mothers)
where T tallness and t dwarfness
eventhough Tt the gene t have its character for height( Tall/drawf… both are related to height)
so only one gene expresses by transcription and translation and here its T and t wont undergo and such process.
similar for tt .
Hope this might help you . I have tried hard to explain if its not clear please
ask me or if you could tell your views . its welcome
