Document Summary
Lecture 9 is: characteristics of str loci that make them useful for forensic dna analysis (dna fin- gerprinting) Str for each person is usually quite unique. Each locus has a different repeated sequence. A given individual is either homozygous or heterozygous for an str allele eg. homozy- gous for the 11-repeat allele or heterozygous for a 9-repeat allele. Each individual has an essentially unique combination of alleles. Analysis of multiple str loci can discriminate between dna of different individu- als: mechanism of dna recombination.
