1. Go to http://www.mtsu.edu/~rseipelt/web2120a/2120pract/2120practped.htm. Determine whether each pedigree is autosomal dominant, autosomal recessive, x-linked dominant, x-linked recessive, or Y-linked. Draw the pedigrees in your notebook and explain, in your own words, why it the answer you chose and can not be the others.

You crime scene binder is due on Tuesday, 5/27/08. It should include the following:

As a group, create one typed narrative report explaining what
happened to these poor people. Be sure to include a timeline of
events. You will state who killed them and explain any evidence you
have to prove it. The evidence reports should be in an appendix and
include a description of how that test, if applicable, is performed
and analyzed. You should reference each “exhibit” within your
narrative report. Include a printed computer version of your crime
scene diagram. Don’t forget to include any necessary witness
statements. Combine all of this in a 3-ring binder. You will get a
group grade for the completeness, accuracy, and organization of this
binder. Completeness will include how much of the case you have
solved.

Finally, each individual will type a one page reflection of what
you have learned beyond specific content. What have you learned
about forensics, or group work, or completing a long term project, or
an open-ended project with little direction, or work ethic, etc…
The report should include what you will do differently on such
projects in the future (ie. in college) You will hand this in
separately from the report.

Test on Monday, 5/19/08 on material you should have learned throughout the crime scene investigation.

There will be a test on Monday, 5/19/08 on the following material:

Nervous system: general information, how neurons work, brain and spinal cord = everything in the supplied notes up to ‘PNS’

Muscular system: in class notes on how a muscle contracts, energy supply, exercise, atrophy, muscle testing, and muscle grading (0-5). You must also be able to identify muscles on a picture and know the origin/insertion/action/innervation information from the handout.

Skin: notes and handouts on the skin layers, skin receptors, skin colors, fingerprints, and items found in the skin (ie. sweat glands, arrector pili muscle etc…)

Forensic hair analysis involves using a light microscope to analyze the hair for various factors to determine the origin of that hair.  Is it a human hair or animal?  Is it a male or female hair?  Can we determine the individual race?  What about the age?  To get an answer to these questions and to learn what to look for in a hair sample, visit this site.  Because examining a hair requires a microscope, be sure you understand how to use a microscope and that you can name all its parts.  For practice using a virtual microscope, go to this University of Delaware site and click on “The Virtual Scope”.

How does one analyze handwriting samples to check for forgeries? Go to the following site for a lesson to learn all about Questioned Document Analysis.
