Problem 2 Suppose a haploid yeast strain carrying two recessive linked markers his4 and leu2 was crossed with a strain that was wild type for HIS4 and LEU2 but had an inversion of this region of the chromosome as shown here as a narrow line. his4 leu2 LEU2 HIS4 Several different kinds of crossover events could occur during meiosis in the resulting diploid. For each of the following events, state the genotype and phenotype of the resulting four haploid spores. Do not consider crossover events between chromatids attached to the same centromere. Please use colored pencils or markers so that the products of the crossover in the crossover structure are easy to follow. I. Consider a single crossover between markers HIS4 and LEU2. a. Draw the crossover structure that would result. b. Draw each meiotic product indicating the location of the genes and the centromeres. For each product indicate if it is normal, contains duplications, contains deletions, or have both duplications and deletions. If a product has a duplicated region, highlight it. Indicate if each product can lead to viable offspring or inviable offspring.
