• Bring a computer diskette to lab unless you know how to send yourself email with attached files
• You don't need to print out the instructions, since you'll be working at a terminal already.
• Instructions for experiment
• The report is due Monday, 27 October, at the beginning of class
•  The Drosophila Virtual Library
• Virtual FlyLab site
• List of Mutations

THE REPORT.  You must turn in a TYPED formal report   for your assigned mutation.   Use the Virtual FlyLab to test this hypothesis: "This mutation is autosomal and recessive to the wild allele."  (or "these mutations are independent and recessive to the wild alleles"  if you're doing a dihybrid cross)   If you reject the hypothesis, you must devise and test an alternative hypothesis.  Follow the same instructions as the previous virtual fly lab for what to include on the report content. <--Here is where to click to get to those instructions.  Maybe you should review the example, too.  But the form and style of the report should be the classic research report style.  It must be typed, but you may draw in the Punnett squares by hand.

• HELP
  • sex-linkage
    • explanation
    • picture
  • Independent assortment pictures
    • dihybrid cross (with 16 squares; it's better to do two small Punnet squares and then multiply)
    • dihybrid test cross (again with 16 squares; too bad)
    • NOT independent

• THE EXPERIMENTS

  Lab 7 is another Virtual FlyLab just like LAB 5 except that this time

  1. you have to work alone
  2. you have a harder problem to do
  3. but you have a choice of harder problems, either a tricky single mutation (the first number in the List of Mutations) or a double mutation dihybrid cross (the second + third number by your name in the List of Mutations).  (your choice of dihybrid or tricky single will not affect your grade)  HELP 
  4. You do have a chance for EXTRA CREDIT (but it counts only if all of the above are done correctly and perfectly so you might want to finish all of the above early and get them checked before you invest more time).   For extra credit do one or both of these:
     a. Add a more challenging mutation, one of these: 5,11,16,19,23,29. (no help available)
     b. If (and only if) you have had MATH 206 or get special permission from the instructor, do chi-square tests or let the Virtual Flylab do them for you.  Be sure to include your null hypothesis, the degrees of freedom, the probability associated with your chi-square value, and your conclusion (rejecting or not rejecting the null hypothesis).
  5. You must turn in a complete formal report, typed (except for Punnett squares)

  Lab 5 is a good place to review the example of how to get the right results and exemplify the scientific method in your report. HELP
