GeneLeaf is a cloud-based application designed to support the analysis of hereditary relationships through a standard pedigree format. Genetics is the study of family relationships which transfer the information that determines the phenotype of each individual in form of discrete hereditary units called genes. Pedigree diagrams allow relationships to be quickly and efficiently documented in a standardized format. In these diagrams, the relationships between individuals are represented through a simplfied set of symbols, related through lines. Gene Leaf enables users to quickly capture information in this form through an intuitive user interface, which supports rapid entry of information.
