A candidate single nucleotide polymorphism (SNP) combination is selected from a plurality of candidate SNP combinations for a gene associated with a genetic trait. Haplotype data associated with this candidate SNP combination are read for a plurality of individuals and grouped into a positive-responding group and a negative-responding group based on whether a predetermined trait criteria for an individual is met. A statistical analysis on the grouped haplotype data is performed to obtain a statistical measurement. The acts of selecting, reading, grouping, and performing are repeated as necessary to identity the candidate SNP combination having the optimal statistical measurement. In one approach, a directed search based on results of previous statistical analysis of SNP combinations is performed until the optimal statistical measurement is obtained. In addition, the number of SNP combinations selected and analyzed may be reduced based on a simultaneous testing procedure.

Secure network transaction system obtains user-authorized genetic term or bioinformatic profile, and transacts online service according to genetically-based user medical or other risk determined therefrom. Insurance policy, promotional offer, or other service may dynamically address genetically-based condition. Bioinformatic data classifies user per personal mask which filters subset of user genetic sequence. Risk profile may be calculated according to actuarial statistics, genetics and/or heredity using non-discriminatory rules specified for users in temporal or jurisdictional groups. User transactions are modifiable according to bioinformatic data representing genetically-based risk increase or decrease. Data is securely processed, modulated, and stored by network server for remote access and transaction using various portable user devices.

A standard and integrated behaviour testing platform used for testing animal optogenetics regulation and control is established by combining an optogenetics neural regulation and control technology and electrophysiology and behaviour tests and the like; by virtue of the platform, optogenetics regulation and control as well as behaviour record on the tested animals in certain environment can be realized, thus being easy to understand relation between the animal optogenetics regulation and control and the behaviour and meeting requirements of research on pathogenesis and treatment mechanism of a nervous system and mental diseases.

Improved systems and methods for performing genetic analyses. Full genomic DNA scans are performed on the genetic DNA from a plurality of individuals to identify genetic variants. For those variants, but not based on a full genetic DNA scan, the variants alone are scanned in additional individuals to identify blocks of the variants that tend to be inherited together.

Systems have been devised for health management based upon genetic markers. Specifically, systems are arranged to compute genetic risk for several factors relating to metabolism and weight gain in view of various genotypes at particular markers in an individual's genome. An algorithm which depends upon these risk calculations and in further view of the presence of additional variants in the genome under test is executed to arrive at a diet type selection for the particular user. In additions to diet type selections, specific supporting diet related recommendations related to eating behaviors, food reactions and nutritional needs, based upon markers found in the genetic profile, are additionally included in a diet action plan.
