profile is the set of alleles that an individual has at a given locus a genotype or dna profile may also comprise the sets of alleles that an individual has at more than one locus by way of non limiting example a genotype or dna profile may comprise the set of alleles at each of at least 2 loci 3 loci 4 loci 5 loci 7 loci 9 loci 11 loci 13 loci or 20 loci a genotype profile includes profiles matched to an individual to identify the individual as potentially having contributed to the sample the genotype profile may be matched to the individual after obtaining a sample from the individual the genotype profile may also be matched to an individual by comparing it to other genotype profiles in a database the database may be any public or proprietary database that stores and or matches genotype profiles the database may be codis which may be used to store genotype profiles in a national state or regional collection and which may separate these profiles into disjoint parts such as a convicted offenders database a forensic dna database or a missing persons database likelihood conditional probability of an event where the event is considered as an outcome corresponding to one of several conditions or hypotheses a non limiting example of an event is the dna profile evidence from a crime stain the probability of the event is conditional upon the hypothesis that may vary if the dna profile is a mixture a typical prosecution hypothesis may be suspect and victim this is written as pr e h where e is the event the vertical bar in between the two terms means u201c given u201d and h is the.
