I understand that DNA can come from hair but also from other places.
Let's suppose a person gets their DNA mapped by a company (there are some companies claiming to offer analysis of DNA.. e.g. maybe $200 and maybe some may send the DNA on a DVD)
I understand from this link that human DNA should fit on a DVD
Would it be possible to get a person's likeness.. if not now, then in future, based on the DNA I might be able to get sent to me digitally.
And presumably the DNA of a 28 year old would be the most ideal for getting (in a computer program) the likeness/image of that person at 28 - the age the DNA was taken?
I hear of the cost of sequencing the human genome to be millions or billions.. Is that more about scientists figuring out what the DNA does, rather than capturing it all?
For example, if I got my DNA captured by a company for $200, then in 50 years time or the future when technology develops, could I use it to produce a likeness of myself? Or would what a company would send me, not really be all my DNA or be vastly insufficient to create a likeness?
I'm interested in if the kind of test that copmanies off for $200 provides all the information to create an exact replica.
Is a complete replica of a person possible in theory? (e.g. if in future they have a machine to build somebody from DNA) (with the information gathered and that could be sent to the customer by a DNA test for $200, or is it impossible even in theory because the DNA collected and sent is insufficient?)
I'm more interested in the possibility of (in theory) getting a really good likeness, than the personality of a person.
If a company only collects Saliva, is that just a fail.. would they need hair too and DNA from all sorts of human parts, in order to get a good likeness? or better likeness? Or would it not matter whether it's the hair or the saliva?
