The cells of triploid individuals have three sets of chromosomes (3n), whereas
diploid individuals have two sets (2n). Triploidy is produced by preventing the
second meiotic division, after the sperm enters the egg. This process results in
two ...

doubling, and to use these in triploid hybrid production. Experience with such
hybrids is ...
