Two haploid yeast strains are crossed together, one wild type, the other mutant for 2 linked genes. The resulting diploid strain undergoes meiosis eventually (=many meiotic events> many asci). A. What will the results be if the 2 genes are very far away from each other (certainly more than 50 map units)? B. What will the results be if the two genes are right next to each other, "no distance at all, zero distance"? (Explain your answers). Results here are patterns of asci and their percentages. Like for example "50% tetratypes, 0% ditypes", etc. If you forgot what a ditype or a tetratype is, you can illustrate them like that.

Question
We have discussed meiosis in yeast. One ascus e one melotic event. Two haploid yeast strains are crossed together, one wild type, the other mutant for 2 linked genes. The resulting diploid strain undergoes melosis eventually (=many meiotic events > many asci). A. What will the results be if the 2 genes are very far away from each other (certainly more than 50 map units)? B. What will the results be if the two genes are right next to each other, "no distance at all, zero distance"? (Explain your answers). Results here are patterns of asci and their percentages. Like for example "50% tetratypes, 0% ditypes", etc. If you forgot what a ditype or a tetratype is, you can illustrate them like that.
