However, even in diploid cells deletions are generally lethal or have other serious consequences. In a diploid a heterozygous deletion results in a cell that has one normal chromosome set and another set that contains a truncated chromosome.

One of the major causes of ploidy is due to the non-disjunction of sister chromatids. This occurs mostly during the meiotic cell divisions. Before undergoing meiosis, the chromosome number is doubled during gamete formation. These mutations in apical meristems results in doubling of growth in plants.
