Cooperative interactions between pairs of homologous chromatids during meiosis in Saccharomyces cerevisiae

Genetics. 2008 Jun;179(2):1125-7. doi: 10.1534/genetics.108.088567.

Abstract

We report a novel instance of negative interference during Saccharomyces cerevisiae meiosis, where Cre-mediated recombination between pairs of allelic loxP sites is more frequent than expected. We suggest that endogenous crossover recombination mediates cooperative pairing interactions between all four chromatids of a meiotic bivalent.
