Centromeres convert but don't cross

PLoS Biol. 2010 Mar 9;8(3):e1000326. doi: 10.1371/journal.pbio.1000326.

Abstract

Geneticists have long known that centromeres suppress crossing over, but considerable evidence indicates that they appear to recombine. Confirmation of gene conversion in maize centromeres explains this paradox.
