Pedigree-Based Estimation of Y-STR Mutation and Male Differentiation Rates: Application to Historical Remains Identification

This high male differentiation rate is advantageous for distinguishing unrelated individuals within the same population, reducing false inclusions. However, when comparing distantly related individuals, excessive mutations accumulated over many generations may obscure genuine patrilineal relationships, increasing the risk of false exclusions. Our findings are likely to be highly valuable for future interpretation of Y-STR haplotypes from patrilineal relatives across a wide range of applications, with significant relevance to historical remains identification casework.
