Can I use DNA analysis to reconstruct parental DNA?

Yes! DNA analysis can reconstruct approximately half of each parent's DNA from your genetic data:

How It Works:

You inherit exactly 50% of your DNA from each parent. Using your DNA file, we can identify and separate:

• Genetic variants inherited from your mother
• Genetic variants inherited from your father
• Specific chromosome segments from each parent

What You Need:

Best Case - Trio Phasing:

• Your DNA file
• Your mother's DNA file
• Your father's DNA file
• Result: Highly accurate (99%+) parental reconstruction

Good Case - Duo Phasing:

• Your DNA file
• One parent's DNA file
• Result: Very accurate reconstruction of inherited segments

Basic Case - Statistical Phasing:

• Only your DNA file
• Uses population reference data
• Result: 85-95% accurate estimation

Applications:

• Genealogy: Trace ancestry to specific grandparents
• Medical: Identify which parent passed health-related variants
• Ancestry Analysis: Separate maternal/paternal ethnic origins
• DNA Matching: Determine relation through specific parent
• Family Research: Reconstruct deceased parent's genetic profile

What Can Be Reconstructed:

• Specific SNPs from each parent
• Chromosome segments and their parental origin
• Ethnic composition by parent
• Haplogroups (direct maternal and paternal lineages)

Limitations:

• Can only reconstruct the 50% you inherited
• The other 50% each parent has is not in your DNA
• Siblings have different combinations (except identical twins)
• Accuracy depends on method and data quality

How to Get Started:

Purchase our Phasing Service (Single or Duo/Trio) from the store to begin parental DNA reconstruction.
