Question
She had her eye on the donut all night. It was round, with a hole in it, and had sprinkles. She wanted it badly, even though it was definitely not carb-free. As she reached for it, someone else was reaching as well. Sprinkles fell to the floor, and the donut was changed forever. After a brief scuffle, only a small piece of blood-smeared donut was found on the floor, next to the battered body of the woman who loved it. Who had beaten this woman? Only the bloodstain on the donut could reveal the answer.
After analyzing the DNA data, answer the following questions:
Is the victim "excluded," "included,” or "not excluded” from contributing to the stain?
* Clearly explain your reasons for each possibility.
The DNA profile from the stain reveals a mixture of at least two individual blood. What is the genetic profile of the other individual?
* Use the CODIS Entry Worksheet.
CODIS can be used to identify the Genetic Profile of the unidentified suspect. How would you use the CODIS Database to identify the suspect in this case?
There are some problems noted by the technician in this case.
Pullup (pu) is found on which locus?
What specific quality control item(s) could account for pullup?
Stutter (st) is found on which locus?

Ans- the victim is included in stain because there are similarities between the markers of victim and stain for e.g. their position on vwa section onthe CODIS graph.
- The graph include profile of two individuals. The profile of the other individual will include the markers on stain graph other than the markers which are present in victim graph.
-the codes database can be used for identification of suspect because the database of the stain codis graph have some markers positioned with different numbers . The codis database which have similar codis graph will be included in contributing stain and will be considered as preptrator
-puulup is found on 17 or 7 locus.
- pullup are produced due to failure of analyzer software to discriminate between two different dyes.
- +4 stutter are present on 19 th locus on D3S1358.
