"There is a hypothesis that polyploidy is favorable because the plant has multiple copies of the haploid genome that permits additional genetic variation in homologous pairing options in Meiosis I. This offsets the inbreeding typical when the gametophyte self fertilizes and reduces the risk of inbreeding depression. http://users.rcn.com/jkimball.ma.ultrane… Polyploid organisms with more than two copies of their genome grow larger cells and organs. Plants have little structural specialization so suffer little or no disruption of function in becoming polyploid. Rather they benefit by having greater genome plasticity when they become polyploids. Extra alleles can drift to new functions. It is estimated that as much as 70% of all plant species have increased genomic content from polyploid expansions. Plants have few gene dosage limiting effects and with more than two alleles for each gene plants are more heterozygous than animals so have greater genome plasticity and genetic drift."
