Is the technology "identitas v1 forensics chip" related to microarray technology?
if true ,as I know, different combination of genes are expressed in different parts of our body which means a certain tissue only makes particular types of mRNA.
Then my question raised: How can a CSI crew reconstruct a person's virtual appearance (for example skin color, face structure) by a piece of microarray with limited tissue (for example cells from saliva) and mRNA? I mean saliva cells don't make pigment of our body, so how can the eye color or skin color be presumed, for example?
Otherwise, what is the technique "identitas v1 forensics chip "which allow us to detect several phenotype simultaneously?
According to the information I Know,"identitas v1 forensics chip" it contains hundreds of thousands of short sequences of DNA that binds to SNPs,where the DNA from the crime scene binds to this chip can allow software to reconstruct the appearance of the person of interest.
the chip is the first to provide data on all these traits simultaneously. Other devices can determine at most two at a time – usually eye and hair colour.
