GENOME CONTRACTION. “Twenty-four ancient plant polyploidies have been documented within plant genomes as of January 2014. In maize, some crucifers, and perhaps all new plant polyploids, fractionation (loss of duplicated genes) and diploidization (return to diploid meiotic behavior) happen within a few million years of the WGD. In the grasses, both fractionation and diploidization are relatively rapid.” (WGD = whole genome duplication).
