In sexually reproducing organisms, homologous recombination increases
genetic diversity in gametes and ensures proper chromosome segregation
. Recent publications have provided details of the molecular intermedi
ates and proteins involved, the control of the distribution of recombi
nation events at the chromosomal level, and the surveillance mechanism
s that coordinate recombination with the meiotic cell cycle. (C) Curre
