Abstract: Determining a genetic sequence for a particular site on an individual's genome is disclosed, including: receiving a measurement associated with a particular sequence for the particular site on the individual's genome, receiving contextual information associated with a context of the individual within a larger collection of genetic information, and using the measurement associated with the particular sequence and the contextual information to compute an improved determination of the genetic sequence at the particular site on the individual's genome.

Abstract: Processing genetic data is disclosed, including: receiving two or more genetic data sets for an individual from one or more genetic data sources; merging the genetic data sets from the one or more genetic data sources, including identifying a duplicate SNP between the genetic data sets and determining one or more data values to be stored for the duplicate SNP; and storing a single set of merged genetic data for the individual.

Abstract: Displaying a comparison of genetic data is disclosed, including receiving an indication of a first individual, receiving an indication of a second individual, retrieving the genotypic information for the first individual and the second individual, comparing the genotypic information of the first individual and the second individual, displaying an indication of the comparison of the genotypic information of the first individual and the second individual graphically. A first graphical symbol is used to display an indication of the genome regions for which the first individual and the second individual are identical. A second graphical symbol is used to display an indication of the genome regions for which the first individual and the second individual are half identical.

Abstract: Displaying a comparison of genotypic information between relatives is disclosed, including receiving an indication that a first individual is a grandparent, receiving an indication that a second individual is a grandchild of the first individual, comparing the genotypic information of the first individual and the second individual and calculating a similarity score, and displaying an indication of the similarity score graphically using colors.
