Central Ltd.   Initiation sites for meiotic recombination have
now been precisely mapped across the budding yeast genome using
a widely applicable deep-sequencing approach.  Meiosis and the
roles of recombination  The consecutive cell divisions of
meiosis precisely halve the cellular chromosome complement to
produce haploid gamete cells. Prior to first division,
replicated paternal and maternal chromosomes (homologs) become
intimately associated before segregating to opposite poles of
the cell. During the second division,
