Abstract
IN many fungi, such as most of the Ascomycetes and Ustilaginales, the products of meiosis are arranged regularly in a linear order, and by examining them or by isolating them in order, it is possible to distinguish between segregation of a pair of allelomorphs at the first and at the second division of meiosis. The relative frequencies of first- and second-division segregation for a given locus are dependent on the frequency of crossing-over between that locus and the centromere of the chromosome. Hence, the centromere can be plotted on the cross-over map of the chromosome.
