Schedule of Experiments
Lab # | Dates | Activity | Outside lab time |
---|---|---|---|
1 | 9/8 - 9/14 | view worm videos; examine wild type and mutant worms; |
3-4 days later: Pick 2 "wild type" looking worms from each cross to self |
2 | 9/15 - 9/21 | score autosomal vs X-linked cross; Mutant Hunt! Pick 3 worms to individual plates |
3-4 days later: cross wild type males by mutant hermaphrodite |
3 | 9/22 - 9/28 | Linkage Test: Cross mutant males by 4 tester strains; Backcross: Pick 2 "wild type" L4's to a new plate |
3-4 days later: Linkage Test: transfer 2 L4's from each cross to new plates |
4 | 9/29 - 10/5 | Linkage Test:Score for linkage Backcross:confirm true breeding line |
