5. If we found AB+ blood at a crime scene and we knew one of our 5 suspects had a partial Genotype that was determined to be IAI B CcEe would this be enough evidence to make this suspect now a lead suspect. Why or Why not? Use Punnett squares to make your case. What additional test would need to be performed? 6. A homicidal maniac has a genotype of IB I B Ccddeehhsese. At this murderer’s most recent crime scene we find the murder’s baseball cap without blood, a pair of stained underwear no blood, no fingerprints, no fibers, no hairs. Based on these items, do we have any possible chemical, or immunological or other analyses we can perform that will identify the murderer as it relates to the genotypic info we have on him or her. If so how would you go about doing those studies Solution 5. ANS: No, At first the D antigen additional test would need to be performed. It is because AB+ is the most common blood group and the the perp would have to be either Dd or DD (Rh+ve). we could only really use the evidence to exclude suspects. 6. ANS: In this case the blood strains are not there. Genetic material on it and use that to identify the genotype is the best way to detects suspect. So genotyping performing will identify the murderer. Genotype is used to determine the alleles that an individual possesses. Genotyping test is used for crime and paternity testing because in genome there is 1 difference present in every 1,000 base pairs (in humans 3,000,000 difference sequence are present)..
