- Mispronouncing as /tetraˈplɔɪd/ (stress on 'ploid'). Correct stress is on the first syllable. Using it as a verb (e.g., 'to tetraploid'). The verb form is 'to tetraploidize' or 'to induce tetraploidy'.
FAQ
Frequently Asked Questions
No, not necessarily. Tetraploidy can occur naturally or be induced. It is a change in chromosome number, not necessarily the insertion of foreign genes.
While extremely rare and not viable for full-term development, tetraploid cells can occur in humans (e.g., in some tumours or in early embryonic miscarriages). No living tetraploid human is known.
An autotetraploid has four sets from the same species. An allotetraploid results from hybridisation between two different species, each contributing two sets of chromosomes.
It often leads to larger cell and organ size (e.g., bigger fruits, seeds), increased vigour (hybrid vigour in allopolyploids), and can create new, fertile species from sterile hybrids.
