Method and system for preparing a personal genetic profile includes collecting genetic data from an individual, assigning the data to a coordinate system, storing the data, and providing access for retrieval by the individual from whom the genetic data were collected, after receipt of an Identifier that adequately authenticates the identity of the data requester. Locations of genetic markers are provided as three-dimensional coordinates, described with matrix relationships that are consistent with the primary and secondary chemical structure of molecular constituents of a DNA chain for the individual.
