6. A diploid strain of yeast was made by mating a haploidstrain with a genotype w−, x−, y−, and z− with a haploidstrain of opposite mating type that is wild type for thesefour genes. The diploid strain was phenotypically wildtype. Four different X-ray-induced diploid mutantswith the following phenotypes were produced fromthis diploid yeast strain. Assume a single new mutation is present in each strain.Strain 1 w− x+ y− z+Strain 2 w+ x− y− z−Strain 3 w− x+ y− z−Strain 4 w− x+ y+ z+When these mutant diploid strains of yeast go throughmeiosis, each ascus is found to contain only two viablehaploid spores.a. What kind of mutations were induced by X-rays tomake the listed diploid strains?b. Why did two spores in each ascus die?

4. When the F1 bees were backcrossed to the inbred resistant line produced 4 types of offspring in equal numbers: ¼ if the back-cross offspring showed the complete hygienic behavior pattern¼ of the back-cross offspring showed none of the elements of hygienic behavior¼ of the back-cross offspring would uncap the cells of the diseased larvae but these workers would not remove the diseased larvae¼ of the back-cross offspring would remove the diseased larvae (once the experimenter had uncapped the cells of the diseased larvae) a. If the resistant behavioral pattern is due to two gene loci with two alleles each, can this account for the 4 phenotypes shown in the back-cross? How? b. If you use UURR (for the non-resistant inbred line) and uurr (for the resistant inbred line), what are the phenotypic and genotypic ratios for the F2 cross between these lines (i.e., F1 x F1)?
