Probabilities of sharing 0, 1, or 2 alleles at 18 loci commonly used in the forensic practice, and for the indicated relationships, ordered by increasing value of heterozygosity (corresponding to parent-child z₁ values); heterozygosity values were computed as weighted means among Caucasian populations.
