The Recombination Frequency around the <i>MAT</i> Locus Is Unusually High

<div><p>(A) The mating of C. neoformans is shown.</p><p>Left, cells of opposite mating type were mixed on V8 mating medium, and the white filaments around the yeast colony edge are dikaryons produced by mating. Right, chains of basidiospores observed by microscopy.</p><p>(B) The meiotic recombination frequency between <i>MAT</i> and flanking markers is indicated in % and as the number of recombinants in the total progeny analyzed. The first letter of the marker indicates the dominant selectable marker (E for NEO^R and T for NAT^R); the following number indicates the approximate distance between the marker and the <i>MAT</i> boundary; and the last letter indicates the relative position of the marker to the <i>MAT</i> locus (L for left and R for right).</p>
