Abstract: Method for simultaneously determining alleles present in a set of loci from at least one nucleic acid sample comprising the steps: a) providing said at least one sample, b) subjecting said sample to a nucleic acid amplification reaction using a primer pair simultaneously primer pairs specific and optimized for each of the loci of a set of at least three loci selected from the group consisting of D2S1360, D7S1517, D8S1132, D9S1118, D10S2325, D11S554, D12S1064, D12S391, D17S1290, D19S253, MYCLl, P450CYP19 and SE-33, and c) evaluating the length and optionally the relative quantity of amplification products obtained from step b) or from the analysis of one or two of the above loci to determine and/or optionally quantify the alleles present at each of the loci analyzed in the set within said sample.

Abstract: A method is provided for determining a genotype by comparing the nucleotide sequence of members of a gene system which flank the polymorphous sections of a locus or loci of interest. In a general embodiment of the method, the nucleotide sequences chosen for comparison (i) contain one or two sequences that are completely conserved between the members of the gene family, where two or more members are selected from different sources, and (ii) the completely conserved sequences flank strongly conserved sections of genetic material. The completely conserved sequences are typically used to amplify, from different sources, the strongly conserved sections of genetic material. The resulting amplified nucleic acid sequences from the different sources are then compared to establish genotypes.
