Kinship DNA Testing in Gallatin, Tennessee
Kinship DNA Testing for Extended Family Questions
Some relationship questions do not fit a simple parent and child test. Kinship testing is built for the more tangled branches of a family tree.
Overview
How kinship DNA testing works
Kinship DNA testing covers relationships beyond direct parentage: half siblings, cousins, and paternal or maternal lineage. It draws on standard markers as well as Y chromosome and mitochondrial DNA analysis when appropriate.
DNA Paternity Solutions helps families in Gallatin, Tennessee choose the right kinship approach for their question, whether it concerns heritage, an estate or a petition.
Matching the method to the family branch
Y chromosome testing follows the father’s line through males. Mitochondrial testing follows the mother’s line through everyone. Standard kinship analysis estimates how closely two people are related. The right choice depends on who is asking and who is available.

Y chromosome testing
Only males carry a Y chromosome, and it passes from father to son largely unchanged. It is useful for questions about a shared paternal line.
Mitochondrial testing
Mitochondrial DNA passes from a mother to all of her children. It helps confirm a shared maternal line across generations.
