Abstract
During meiosis homologous chromosomes normally pair, undergo reciprocal recombination, and then segregate from each other. Distributive disjunction is the meiotic segregation that is observed in the absence of homologous recombination and can occur for both nonrecombinant homologous chromosomes and completely nonhomologous chromosomes. While the mechanism of distributive disjunction is not known, several models have been presented that either involve or are completely independent of interactions between the segregating chromosomes. In this report, we demonstrate that distributive disjunction in Saccharomyces cerevisiae is preceded by an interaction between nonhomologous chromosomes.Entities:
