31. A wide range of ploidy variation occur to the complex, for example diploid, tetraploid, hexaploid, octoploid, and even dodecaploid.

32. The root yield and sugar content of tetraploid lines were higher than that of diploid lines. However, the Cercospora leaf spot resistance had no significant differences.

33. Cycling meiosis and fertilization events produces a series of transitions between alternating haploid and diploid states.

34. In addition, several copies of conserved syntenic regions exist in Brassica, which supports the hypothesis that of the Brassica diploid species are evolved from a hexaploid ancestor.

35. The results showed 16 of 30 specimens from keratinized type of basal cell epithelioma were aneuploid and 30 specimens from trichoepithelioma were all diploid.

36. In the presence of water, sperm from the antheridia swim to the archegonia and fertilisation occurs, leading to the production of a diploid sporophyte.

37. Androgenetic diploid cloning fishes were induced by thermal shock after fertilization of inactivated Crucican carp eggs with the mature spermatozoas of Singuo red carp .

38. Comparative study of gonadal development of male diploid and triploid oyster, Crassostrea gigas was made by means of flow cytometry (FCM).

39. 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.

40. Based on the basic model of heterosis process study,(sentencedict.com/diploid.html) the resultant genetic vibration theory of heterosis mechanism was proposed according to the resultant action of the same genes in diploid crops.

41. It is difficulty to select and breed apomictic germplasm among diploid rices at present, but it has become a hotspot to select and breed apomictic germplasm among polyploid rices.

42. The identification results of cell ploidy in the material induced showed that most strains were mosaic with diploid and tetraploid cells at average levels of 79.4% and 20.6% respectively.

43. Reduction division --- The first meiotic division, so called because at this stage the chromosome number per cell is reduced from diploid to haploid.

44. The haploid plant produces gametes mitotically and is thus termed the gametophytes while the diploid plant produces spores meiotically and is called the sporophyte .

45. Under the same temperature, the electrolyte exosmosis rate of tetraploid plants were lower than diploid plants.

46. For example, in the unicellular chlamydomonas the vegetative cell is haploid, and the only diploid cells are the zygospores, which germinate to produce haploid zoospores.

47. Androgenetic diploid clones of Paramisgurnus dabryanus were induced by heat shock.

48. One complex number is used to denote each diploid and define the genetic operators.

49. Diplont A diploid organism that represents the vegetative stage in life cycles in which haploidy is restricted to the gametes.

50. Haplobiontic Describing life cycles in which only one type of somatic body is formed, which may be either haploid or diploid, i. e. either the sporophyte or the gametophyte generation is missing.

51. The fungus is unicellular and exists in both haploid and diploid phases.

52. Then in view of the disadvantages of the traditional genetic algorithm for UTP, the diploid code was put forward and alternate evolution was used to optimize multi-targets one by one.

53. Comparatively , PCR - Acc molecular marker produced two genotypes , G - type and T - type for both autotetraploid and diploid rice.

54. The traditional vinca rosea cultivated is the diploid variety, it is necessary to carry on ploidy breeding to enhance its quality.

55. Diplobiontic Describing life cycles showing a typical alternation of generations with haploid and diploid somatic bodies.

56. European nations devided are divided as to whether to diploid deploy them in airports.

57. The endosperm, which is derived from two polar nuclei fusing with one sperm, is a triploid tissue whose genetic constitution is more complex than common diploid tissue.

58. Pro , Tyr, His , Arg in diploid type could not be determined.

59. A gamete containing a diploid number of chromosomes, rather than the usual haploid number.

60. The difference of mantle between diploid and triploid is analyzed from outward appearance, tissue slides and content of protein and glycogen in Crassostrea gigas.
