The results showed that the basic chromosome number of ural licorice was X = 8 and that of membranous milkvetch was X = 7. They were diploids and their karyotypes were 2B and 1A. Karyotype formula were 2n = 2X = 16 = 14m+ 2sm and 2n = 2x = 16 = 14m.
Plants were regenerated on the medium containing low concentration of plant growth regulators and sucrose, and the percentage of haploids, diploids, tetraploids and aneuploids were 4.3%, 64.5%, 17.2% and 14.0% respectively.
Soybean evolution from the ancient tetraploid flowers pollinate crops since the diplont, low level of genetic variation within species, genome larger and contains extensive areas of reproduction and rich repeat sequences, chromosome and small cells to carry out genetic research, which makes soybean genetic map study clearly behind other crops.
Cymbidium goeringii is a diploid and nonrewarding, bumblebee-pollinated species, which is distributed in China, Japan and Korea Peninsula.
The yield of RF biosynthesis in some meiotic segregants was significantly higher than that in segregants from the diploid rib81/RIB81.
The tested primers worked efficiently on the DNA isolated from both diploid and haploid tissues.
The cell hybrids with a near-diploid chromosome set preserve the high-level pluripotency properties of the embryonal partner including the capacity to form chimeras after their introduction in the blastocoel.
The diploid set of both populations included 24 chromosomes (2n = 24).
A significant increase in the rates of diploidy, hypoploidy, hyperploidy of sex chromosomes, and chromosome structure rearrangements in spermatozoa of the patient in comparison with spermatozoa in the control group was recorded.
The diploidy frequency was significantly higher in spermatozoa with large and amorphous heads compared to the control group (2.36, 3.29, and 0%, respectively).
Before treatment, DNA diploidy was seen in 18 cases including 12 p53- cases, and DNA aneuploidy in 12 cases including 9 p53+.
After therapy, aneuploidy could be transformed into diploidy.
Before treatment, DNA diploidy occurred in 18 cases including 13 p21 negative ones, and DNA aneuploidy was revealed in 12 cases including 8 p21 positive ones.
