Paternal Lineage (Y-STR) Testing
Paternal Lineage (Y-STR) Testing relies on portions of human DNA that are passed from father to child relatively unchanged through many generations. One could say that by examining these key parts of our DNA, our paternal history could be traced as far back as the first peoples who populated the earth. Scientific data shows that modern humans evolved in Africa 400,000 to 130,000 years ago, and started migrating outward.
The paternal lineage test is based on the fact that the Y chromosome is passed down from father to child relatively unchanged through several generations. Special sections on the Y chromosome, called short tandem repeats (STRs), are examined to determine a person's Y haplogroup—revealing the geographic origins of his ancestors as evidenced by common DNA markers.
When you purchase a Paternal Lineage Test, you will receive:
• DNA Sample Collection Kit: Easy-to-use, contains cheek swabs and complete instructions.
• Personalized Certificate PDF: Displays your haplogroup designation and map showing your ancestors' journey and where they initially settled in the old world. Results accessed online.
• Lineage Results Manual PDF: Explains your results in detail and provides more information about ancestry testing and human migration history. Results accessed online.
*Residents of CA, MD, NY States require the testing to be ordered by a licensed healthcare provider in your state. Please include a prescription for testing when sending in your sample.
