Kinship index calculation

1. Calculation setting

(1) Y-STR haplotypes    Example
  DYS19 DYS389I DYS389II DYS390 DYS391 DYS392 DYS393 DYS385 DYS438 DYS439 DYS437 DYS448 DYS456 DYS458 DYS635 YGATAH4
Haplotype 1
Haplotype 2
- Single-step mutation (expansion or contraction) is only considered in this calculation.
- The haplotype including mutation should be provided as Haplotype 2 (not Haplotype 1).
- In a Y-STR locus, two or more allele values should be separated by commas (e.g., "10,21" or "10,11,14")
- Blank (no input allele value) is excluded from calculation of kinship index.
(2) Reference group
