Genealogical DNA testing firm Family Tree DNA this week launched its Family Finder DNA test for connecting family members across all ancestral lines. The test uses Affymetrix's Axiom genotyping platform and its GeneTitan system to match a wide range of family relationships within five generations.
Specifically, Family Finder enables customers to look for connections such as grandparents; aunts and uncles; half siblings; and first, second, third, and fourth cousins. The company's previous tests revealed only connections along specific paternal lines or maternal lines.
The test analyzes the DNA of two individuals using Axiom Array Plates containing nearly 570,000 genetic markers, including many that are relevant to genealogy. Family Tree DNA then analyzes the resulting data with internally developed algorithms to determine the closeness of the relationship, the companies said.
