Question
On lab day, you will be given a set of plates that have three yeast strains on them: “a" and “alpha” parental haploid strains, and the diploid strain from the mating of “a” and “alpha”. The genotypes of the parent strains are:
“a” strain: MATa hom3 TRP2 ade2
“alpha” strain: MATalpha HOM3 trp2 ADE2
Predict the phenotype of your lab strains using the genotype information above. In the table below, write “growth” for the strains that will grow in the media and “NG” for the strains that will not grow.
