Remember From The Lecture That We Can Create A Short Tandem Repeat Str Profile Which Identifies The Two Alleles That 1 (74.85 KiB) Viewed 80 times

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) [2 marks] (b) How many possible heterozygous genotypes are there for locus VWA, that could be made up of the alleles listed in the table? [2 marks]
