K2. A geneticist crosses a his4 LEU2 strain to an HIS4 leu2 strain to create a doubly heterozygous diploid (all capital letters means the gene is wild type; lower case letters indicate a mutant allele). The diploid is put through meiosis and the genotypes of the spores in 300 asci were scored as follows: his4 leu2 his4 LEU2 his4 LEU2 his4 leu2 HIS4 leu2 his4 LEU2 HIS4 LEU2 his4 leu2 HIS4 leu2 HIS4 LEU2 HIS4 LEU2 HIS4 leu2 12 138 150 What is the map distance in centimorgans (CM) between the two genes?
