Spindle Positioning, Meiotic Nonreduction, and Polyploidy in Plants
... Polyploidy, the state of having more than two sets of chromosomes, is common in flowering plants (angiosperms), including the major crops [1]. Indeed, it is estimated that 30%–80% of the angiosperms are polyploids [2], and most diploid plant species, including Arabidopsis thaliana, show evidence of ...
