WebPotential null alleles resulting from allele drop-out can be predicted by statistical analysis of the STR typing data. The observed number of homozygotes can be compared to the expected number of homozygotes based on Hardy–Weinberg equilibrium (Chakraborty et al. 1992).An abnormally high level of homozygotes would indicate the possible presence of …
