The synaptonemal complex protein, Zip1, promotes the segregation of nonexchange chromosomes at meiosis I.


Crossing over establishes connections between homologous chromosomes that promote their proper segregation at the first meiotic division. However, there exists a backup system to ensure the correct segregation of those chromosome pairs that fail to cross over. We have found that, in budding yeast, a mutation eliminating the synaptonemal complex protein… (More)
