Transcribed Image Text:Remember from the lecture that we can create a short tandem repeat (STR) profile, which identifies the two alleles that are present at each locus in a series of loci. For our forensic purposes, we might be interested in the frequencies of particular pairs of alleles at a given locus. Here, we consider a locus called VWA, for which we provide a list of allele frequencies: Allele 13 14 15 16 17 18 19 20 21 Frequency 0.002 0.094 0.111 0.2 0.281 0.2 0.104 0.005 0.003 (a) Suppose that saliva was recovered at a crime scene and the genotype VWA(13,15) was identified from this. A suspect was apprehended who matched this genotype. Assuming Hardy-Weinberg equilibrium, what is the evidential value of this match? (round your answer to three decimal places) (b) How many possible heterozygous genotypes are there for locus VWA, that could be made up of the alleles listed in the table?
