We would like to thank Dr. Phil Hartman of Texas Christian University for developing this series and providing us with the worms for our crosses.

Schedule of Experiments
Lab # | Dates | Activity | Outside lab time |
---|---|---|---|
1 | 9/8 - 9/14 | Worm Husbandry: view worm videos;
|
3-4 days later: Pick 2 "wild type" looking worms from each Autosomal vs X-linked cross to new plates |
2 | 9/15 - 9/21 | Score autosomal vs X-linked cross; Linkage Test: Cross mutant males by 4 tester strains; |
3-4 days later: Linkage Test: transfer 2 L4's from each cross to new plates (4 plates total) |
3 | 9/22 - 9/28 | Linkage Test:Score for linkage Mapping:Pick 5 Dumpy worms to individual plates |
3-4 days later: Mapping: Pick 3 double mutants (unc and dyp) to separate plates |
4 | 9/29 - 10/5 | Mapping: cross N2 males with double mutants Complementation: Pick males from Complementation cross #1 and mate with known Dpy strains |
3-4 days later: Mapping: Pick 3-4 heterozygous males to separate plates (8 males total) and mate with homozygous recessive dpy unc worms |
5 | 10/6 - 10-14 | Mapping: Score and determine map distance between unknown Dpy gene and Unc reference mutation |
