(Note:
all the mutant alleles and strains referred to can be found in the FGSC stock
list.)
1.
Screening for morphological mutants (after UV or nitrous acid mutagenesis).
2.
A simple complementation test (al-1 aux-1
+ al-2 aux-2). Aux represents any
auxotrophic allele.
3.
Using the per mutation to deduce the
origin of the perithecial wall. (barrage in cross fl x fl per)
4.
Reversion of ad-3 base pair
transition mutations
5.
Ascus patterns in crosses of normal x rearrangements unknown to the student.
6.
Senescence “lifespans” in kalilo
plasmid-containing strains, measured by serial subculturing.
7.
Reconstructing the arginine pathway. (See G J Stein 1973 Laboratory Exercises
in Genetics, Collier-Macmillan, New York, for FGSC strains and methods.)
8.
Effect of temperature on growth of cot-1.
9.
Selection for methyl tryptophan resistance. (This is an easy selection for
forward mutations at one gene locus mtr.)
10.Suppressors
of morphological mutations.
11.
The mitochondrial mutant poky:
crosses and cytochrome spectra. (See The Experimental Geneticist by P Saint
Lawrence et al., 1974, W H Freeman & Co new York.)
