Tagko refers to a scientific process in genetic manipulation. I own a few genetic related domains as Purdue and Dow Chemical are close to where I am. Mostly students viewing them. I put agrogenetics.com up for sale but really have not got much input on it. Bought it thinking about the process of mass production of corn for use in gas. I think these types of domains might be better suited to a .edu As far as a generic domain. Its going to be some time before 5 letter domains without good keywords will be worth alot. perhaps regfee at best now?
from a laymans perspective, it is one of those BRANDABLE names which can be used for any site i would say low XX to a reseller high XX to a end user
