Explanation:

1. Polyploidy: the condition in which a normally diploid cell or organism gain one (triploid), two (tetraploid) or more additional sets of chromosomes. Polyploidy arises as the result of total non-disjunction of chromosomes during metaphase of mitosis or meiosis, in which the chromosome are not separated during cell division
