Gramps, formerly GRAMPS (an acronym for Genealogical Research and Analysis Management Programming System), [2] is a free and open-source genealogy software. [9] It is developed in Python using PyGObject and utilizes Graphviz to create relationship graphs. Gramps represents a form of commons-based peer production, [10] created by genealogists ...

Genealogy software products differ in the way they support data acquisition (e.g. drag and drop data entry for images, flexible data formats, free defined custom attributes for persons and connections between persons, rating of sources) and interaction (e.g. 3D-view, name filters, full text search and dynamic pan and zoom navigation), in reporting (e.g.: fan charts, automatic narratives ...
A pedigree chart is a diagram that shows the occurrence of certain traits through different generations of a family, [1] [2] most commonly for humans, show dogs, and race horses. [ citation needed ] Definition

[1] [5] [6] The GeneCards database provides access to free Web resources about more than 350,000 known and predicted human genes, integrated from >150 data resources, such as HGNC, Ensembl, and NCBI. The core gene list is based on NCBI, Ensembl and approved gene symbols published by the HUGO Gene Nomenclature Committee (HGNC).
This is a list of gene families or gene complexes, i.e. sets of genes which are related ancestrally and often serve similar biological functions.These gene families typically encode functionally related proteins, and sometimes the term gene families is a shorthand for the sets of proteins that the genes encode.
