Meiosis: Disentangling polyploid chromosomes with supercharged crossover interference

Meiosis depends on the cell's ability to match each chromosome to its homolog in a strictly pairwise fashion. A new study describes an elegant mechanism that tetraploid Arabidopsis arenosa plants evolved to faithfully connect and segregate pairs of homologous chromosomes.
