Genetic

Genetics deals with the molecular structure and function of genes, with gene behavior in the context of a cell or organism (e.g. dominance and epigenetics), with patterns of inheritance from parent to offspring, and with gene distribution, variation and change in populations. Given that genes are universal to living organisms, genetics can be applied to the study of all living systems, from viruses and bacteria, through plants (especially crops) and domestic animals, to humans (as in medical genetics).

Although genetics plays a large role in the appearance and behavior of organisms, it is the combination of genetics with what an organism experiences that determines the ultimate outcome. For example, while genes play a role in determining an organism's size, the nutrition and health it experiences after inception also have a large effect.


Genetic genealogy

Genetic genealogy is the application of genetics to traditional genealogy. Genetic genealogy involves the use of genealogical DNA testing to determine the level of genetic relationship between individuals.

Family Tree DNA

Projects create opportunities for people to work with others to explore their common genetic heritage. Family Tree DNA encourages customers' participation in projects. Membership is free and voluntary. Members may join or leave a project at any time.

Family Tree DNA Projects are run by unpaid volunteers who have an interest in the history and genealogy of a particular haplogroup, lineage, geographic region, ethnic group, or surname. They are given access to tools to compare results and are responsible for managing and organizing the data for their projects.
