Abstract: Methods are disclosed for analysing genetic data about an organism. In one arrangement, input units are derived from studies that provide information about the association between genetic variants and phenotypes. Input units are assigned to one of a plurality of clusters, based on an assessment of the extent to which input units share genetic variants that affect any aspect of the phenotype corresponding to each input unit or any of the underlying biological mechanisms of the phenotype, thereby identifying phenotypes that share underlying biological mechanisms.

Abstract: A method of determining an allelic type of a specific individual, comprising: accessing a database of genetic information on a plurality of individuals, the genetic information comprising: the allelic type of each individual; and the type of each of a plurality of genetic markers for each individual; categorizing the data in the database into a plurality of groups of individuals, such that all individuals having the same allelic type are in the same group, and each group represents a different allelic type; inputting data comprising the type of each of a plurality of genetic markers of the specific individual having an unknown allelic type; specifying a set of genetic markers for which type information is known both for the individuals in the database and for the specific individual; applying a population genetic model to calculate the likelihood of sampling, from some or all of the groups in turn, the input type data of the specified set of genetic markers for the specific individual; and determining the
