2. Hybrid sterility is sometimes overcome by polyploidy.

3. Allopolyploidy A type of polyploidy involving the combination of chromosomes from two or more different species.

4. Unreduced gametes are common in plants and likely represent the most frequent route to polyploidy .

5. 24 Finally, we demonstrated that EBNA2-induced polyploidy is due to both DNA endo-replication and cytokinesis failure.

6. In vertebrates, polyploidy tends to be lethal, but plants can do just fine with all this extra genetic material.

7. The key difference between Aneuploidy and polyploidy is that the Aneuploidy is a condition that happens due to a missing or an extra chromosome in the genome of an organism while the polyploidy is a condition when a cell contains more than two sets of chromosomes.

8. DNA replication begins early in the stadium and is followed, not by mitosis but by Amitotic division, followed by endomitosis and polyploidy

9. Endomitosis The duplication of chromosomes without division of the nucleus, causing polyploidy and leading to an increase in nuclear and cytoplasmic volume.

10. In order to improve the yield and quality of Danshen, a research project of polyploidy breeding by tissue culture was done.

11. In the seventh chapter, Dobzhansky discusses polyploidy, a condition (common in plants) where an organism has more than two complete sets of chromosomes.

Trong chương thứ bảy, Dobzhansky thảo luận về thể đa bội, một hiện tượng (phổ biến ở thực vật) mà sinh vật có nhiều hơn hai bộ nhiễm sắc thể.

12. Polyploidy: numerical chromosome aberrations in cells or organisms involving entire set(s) of chromosomes, as opposed to an individual chromosome or chromosomes (aneuploidy).

13. The observation and statistics of morphology suggested that the hybrids showed interspecific morphological traits and some traits resembled more closely with the higher polyploidy parents.

14. Breeders have bred a great deal of new flower varieties by taking routine cross breeding, radiation breeding, tissue culture breeding, polyploidy breeding, and spaceflight breeding etc.

15. The form of Agamospermy most commonly associated with polyploidy is gametophytic apomixis, in which a female gametophyte (embryo sac) forms with the sporophytic chromosome number (Pessino et …

16. If each ploidal level (cytotype) is viewed as a cryptic biological species, then the contribution of polyploidy to biological species diversity is even higher than previously surmised .

17. In plants, they can come from polyploidy, a process in which seeds, through a quirk in cell division, wind up with an extra copy of their DNA.

18. The results suggested that obvious difference of chromosome number appeared among these Alnus species, even in the same species from different population, and spontaneous polyploidy might occur.

19. The results revealed the practicability of ion beam implantation technique in creating new polyploidy idioplasm, which could provide a new approach for searching the material with apomixis.

20. Aneuploidy: any deviation from the normal diploid (or haploid) number of chromosomes by a single chromosome or more than one, but not by entire set(s) of chromosomes (polyploidy).

21. The polyploidy cell masses and the haploidy cells appeared in the tissue cultures will not result in the hereditary variability and the changes of the character in the original diploid species.

22. Similarities among these species include radial symmetry about the longitudinal axis, an elongate shape, a distinct acrosome, and the presence of endonuclear canals. Noteworthy differences include a smaller total length and width than stellate and white sturgeon sperm cells.
