Abstract

In kinship testing, the level of genotypic similarity between individuals at suitable genetic markers is utilised to assess their degree of familial relationship. Inference is made either by evaluating the available genotypic information under different hypotheses about kinship, represented by different pedigree structures, or through the direct quantification of kinship coefficients using a statistical approach. One complicating factor in genetic kinship testing, however, is population structure whereby the assumption of statistical independence between genotypes of unrelated individuals, or between genotypes at unlinked markers, may become violated. Similarly, physical linkage between markers can also render the simple, so‐called ‘product rule’ for composite likelihood calculation invalid. In these instances, specific statistical approaches and computer algorithms need to be used that properly adjust the relevant computations for population structure or linkage.
