Scientific Background

Autosomal DNA matches are measured in centimorgans (cM). Full siblings inherit distinct recombinations from both parents (~2200–3400 cM), while half-siblings share exactly one parent (~1300–2300 cM). Longer segments indicate more recent shared ancestry.

Most Probable Relationship

Estimated Likelihood: 99.4% based on 2550 shared cM across 68 autosomal segments.
