查询词典 chromosome number

Discussions are given of the fate of Ms2 during translocation in the hexoploid triticale, the exchange of the names for 4A and 4B chromosomes in common wheat and the possible expoitation of the new locus Ms2 (4BS), and the following speculations are made: In geneic genes of allopolyploid organisms the donor chromosomes tend to be intergenomically translocated to their phylogically and evolutionarily close chromosomes with the same order number and the same arm; it is cofirmed that the 7th International Conference of Wheat Genetics was right to exchange the names between chromosomes 4A and 4B of common wheat in 1988; and as a new genetic marker and a breeding tool for all the chromosome B-carrying species in the tribe of Tritceae, Ms2 (4BS) may have wide application in building and expanding the gene pool of germplasm resources of various species of wheat.

对 Ms2基因在六倍体小黑麦与原太谷核不育小麦远缘杂交中易位时的走向，普通小麦4A与4B染色体的互换更名以及 Ms2(4BS)新位点的开发利用进行了讨论：认为异源多倍体生物核基因的组间易位倾向于从供体染色体向进化亲缘关系较密切，且染色体序数与染色体臂相同的部分同源染色体易位；1988年第7届国际小麦遗传学会对普通小麦4A与4B染色体的互换更名是正确的； Ms2(4BS)作为一个新型的遗传标记，作为小麦族内所有携带B染色体组的物种的育种工具和在拓建各类小麦种质资源的基因库等方面均有广泛的用途。

Aneuploid describes chromosome numbers which are not multiples of the haploid number.

Chromosome numbers which deviate from the normal number of chromosomes for a species are said to be heteroploid.

偏离了一个物种的整个染色体数目的叫做导倍体。

Three kinds of chromosome morphology could be observed under oil immersion lens. The first type was condensed, which could be counted in total, but the band could not be seen. The second type was chromatosome that spread completely in the center of equatorial plate and were in metaphase. In this phase, total numbers and band were seen clearly. Last type-chromosomes had already folded and moved towards two poles and concentrated gradually, the total number of chromosomes could be counted, but banding could not be seen clearly.

在油镜下镜检可见3种染色体形态，一种呈高浓缩状态的染色体，可计数染色体总数，但不能显出带纹；第2种是已完全展开并铺于赤道板上的处于分裂中期的染色体，染色体总数和带纹显示都非常清楚；第3种是染色体已折转并向两极移动，并逐渐开始浓缩，染色体总数可以计数，带纹不能清楚显示。
