| Structural alterations of chromosome 2 in Leishmania major as evidence for diploidy, including spontaneous amplification of the mini-exon array. |
| The Rickettsia appear to be essential for development of oocytes and may be important in restoring diploidy in the oocytes. |
| Like the gregarines, however, the life cycle is primarily haploid, with diploidy only occurring before meiosis. |
| Multicolor fluorescence in situ hybridization analysis of aneuploidy and diploidy frequencies in 225,846 sperm from 10 normal men. |
| Although sporulation is a clear indication of diploidy, the absence of sporulation is uninformative since some diploids sporulate at very low frequencies. |
| A second hypothesis stated that ferns accumulated chromosomes through cycles of polyploidy events, followed by a return to genetic diploidy through gene silencing. |
