In this project, we were presented with a crime report and an assortment of evidence from the scene. Our job was the run tests on the evidence and then decide who we thought was the culprit. Next we had to present our case in front of a judge in order to obtain an arrest warrant.
In order to test the different pieces of evidence, we used:
Chromatography: We used ink chromatography in order to find what type of pen was used to write a threatening note found at the crime scene. Further explanation on this can be found in the power point below.
DNA fingerprinting: For the DNA fingerprinting we used gel electrophorisis to find the DNA pattern/fingerprint of a sample found at the scene. Further explanation on this can be found in the power point below.
Fingerprinting: For the fingerprinting we used fluorescent powder and a black light in order to reveal the fingerprint that was found at the crime scene. Further explanation on this can be found in the power point below.
Pedigrees: We used the pedigree to find any family relations or possible genetic diseases among the suspects. This helped us in discovering that Norma Nanny had a 75% chance of having Huntington's Disease. Further explanation on this can be found in the power point below.
Karyotyping: We used karyotyping to find any chromosomal disorders in the suspects. This helped us in discovering that Norma Nanny had XXX chromosomal disorder. Further explanation on this can be found in the power point below.

What I learned about:
Human Genetics/Inheritance: Throughout this project and unit, I learned a lot more about creating Punnet Squares. We also learned about dominant and non-dominant alleles and how they affect the characteristics of offspring.
Genetic Diseases: I learned more about how genetic diseases are passed down and I also learned that they cause chromosomal disorders.
Chromosomal Abnormalities: I learned more about what chromosomal disorders look like at the chromosomal level and what chromosomal disorders cause.
DNA Fingerprinting/Sequencing/Forensic Science: I learned how DNA has its own fingerprint that can be revealed through electrophorisis. I also learned a lot of things about Forensic Science and how the evidence that you get isn't always clear cut.
I give this project two thumbs up because I thought it was interesting to run all the tests and it gave the lesson a little extra excitement since we were trying to find a hypothetical killer. It also gave us an idea of what the criminal justice system is like and what it's like to work in that field. I also really liked the guest speaker because it was a very interesting presentation.
