Corrigendum

In the article by David T. Kirkpatrick, John R. Ferguson, Thomas D. Petes and Lorraine S. Symington (Genetics 156: 1549-1557) entitled "Decreased Meiotic Intergenic Recombination and Increased Meiosis I Nondisjunction in exo1 Mutants of Saccharomyces cerevisiae", on page 1554, second column, line 28, the given P value for the his4-lopc strains (p = 0.03), showing a significant increase in PMS tetrads when EXO1 was deleted, is incorrect. The correct P value is P = 0.4, indicating no significant increase in PMS tetrads among those tetrads exhibiting aberrant segregation in these strains. This correction does not affect the major conclusions of the paper.
