Answer

The full explanation

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.
