You are a forensic technician working on a dna sample obtained from a crime scene. your job is to compare the unknown dna sample with known dna samples collected from five different suspects. preliminary analysis using only a few dna markers revealed that the unknown sample could possibly match two of the suspects. after consulting the case file, you find out that these two suspects are brothers (but not twins). you realize that you will have to do a more detailed analysis on the samples so that you can distinguish between the brothers and determine which brothers' dna matches the unknown sample. why can't you use mitochondrial dna to distinguish between these two suspects?
