Gene conversion in Arabidopsis tetrads.
Mendel established that heterozygous alleles typically segregate in a 2:2 ratio during meiosis. The molecular events that accompany meiotic recombination can also cause a nonreciprocal exchange of information between parental chromosomes that results in a non-Mendelian 3:1 segregation pattern called gene conversion. In this issue, Sun et al. use a visual, pollen tetrad–based assay to measure the frequency of gene conversion across the genome of the model plant Arabidopsis thaliana.
