Simply so, what is the purpose of genealogy?

Genealogy is a very important task for any family. It provides a way to connect with the past while building a future. It gives people a sense of where they came from, while also creating a sense of pride.

Similarly, why do I need to trace my roots as a person? Others trace their ancestors because they want to know about their different ethnic backgrounds. Others want to trace their roots simply for an increased understanding of just who they are and where they came from. Someone else may need proof of their heritage to gain special benefits from their government.

Correspondingly, what is the difference between genealogy and ancestry?

They both involve seeking information about your ancestors so what is the difference? Genealogy is the study of ancestry and descent and refers more to the actual search for ancestors and descendants, with your pedigree being a single direct line backward from yourself.

How does genetic genealogy work?

A genealogical DNA test is a DNA-based test which looks at specific locations of a person's genome, in order to find or verify ancestral genealogical relationships or (with lower reliability) to estimate the ethnic mixture of an individual. Autosomal tests are also used in estimating ethnic mix.
