Abstract: The invention provides a method and system for conducting genetic research using DNA sampling, preferably via an online social network, using a set of family members related by defined genealogical relationships to identify carriers of a DNA of interest for obtaining DNA information. According to various aspects of the invention, the method can be used for identifying and determining carriers of a DNA of interest, and further genealogical analysis.

Abstract: A method and system for generating an interactive computerized biological network consisting of living and non-living entities based upon the multiple relationship types which can exist between entities. The network can consist of multiple node types. Such node types can include persons, places, objects, and animals, each connected by one or more linkages associated with a precise linkage type representing the relationship type between a node and any other node type in the same network. Nodes are connected to other nodes in the network by linkages which can have multiple linkage types. Each linkage type represents the actual relationship type between the nodes, such as person, place, object or animal represented by the nodes.

Abstract: A method of constructing family trees wherein users access a web site of an online social network and interactively contribute information to the family tree. The ability of the user to add or edit the information in that user's family tree depends on whether the user is active within the system.
