1) Pretend you are investigating a newly seized tusk and wonder if the tusk is from a recently discovered crime where 10 elephants from the same population were found dead with their tusks removed. The genotype of the seized tusk for five short tandem repeat (STR) loci is shown in Table 1. Allele names for each of the STR loci correspond to their size in base pairs (bp). Table 2 lists the genotypes of the same five STR loci for 10 recently slaughtered elephants. C. a. Did the seized tusk come from one of the recently slaughtered elephants? If so, which one, or if no, why not? The seized fusks came from elephant #8. This is because the seized elephants matches Perfectly with the decreased, PCR. Since everyone has DNA that is unique, it was an obvious match- b. For each of the 5 STR loci, draw the expected pattern of bands on the gel below. Show the alleles for the seized tusk and the elephant you identified as a potential match. Also, include a DNA ladder that has DNA fragments that are 75, 125, 150, and 175 base pairs (bp) in size.
