染色体数 meaning in Chinese
chromosome number
Examples
- Generally meiosis occurs before gamete formation , resulting in the gametes being haploid ( having half the normal number of chromosomes )
在配子形成前通常会发生减数分裂，产生单倍体的配子（染色体数为正常的一半） 。 - Euploidy the normal state in which an organism ' s chromosome number is an exact multiple of the haploid number characteristic of the species
整倍性：正常状态下，生物体染色体数是此种生物单倍体数目整数倍的现象被称为整倍性。 - Examination of chromsome number of the hybrids ri showed the sum of both parent chromsome besides aneuploid . the hydrid cell line ri was characterized by isoenzyme analyses , sds - page , rapd and opine synthetase assay
杂种r _ 1细胞的染色体数检查、冠瘿碱检测、同工酶分析，可溶性蛋白sds - page电泳和rapd分析结果，都证明了其杂种特性。 - The appearance of the gynogenetic fish was similar to that of f2 hybrids , the diploid gynogens were able to produce diploid eggs that were proved by the presence of the triploids with 150 chromosomes among the offspring produced by mating the diploid females of the gynogens with the diploid males of the red crucian carp
在第三年可育的雌核发育鱼的比例有所增加。在外形上与湘螂fz相似，在繁殖特性上，二倍体雌核发育鱼也与湘螂fz相似，能产生二倍体卵子，其与红螂后代的染色体数为3n = 150 。 - The karyotype of caragana microphylla lam can be espressed as 2n = 16 = 16m ( 4sat ) ; the chromosome number of c . intermedia kuang et h . c . fu is 2n = 18 . the karyotype of c . intermedia kuang et h . c . fu can be espressed as 2n = 18 = 16m ( 4sat ) + 2m ; the chromosome number of c . arborescens ( amm . ) lam is 2n = 20 . the karyotype of c . arborescens ( amm . ) lam can be espressed as 2n = 20 = 20m ( 4sat ) ; from the conclusion one and two , we can guess : the c . intermedia kuang et h . c . fu ' may be the hybrid or intermediary genve between caragana microphlla lam and c . arborescens ( amm ) lam , also may be have different haploid chromosome number
( 2 )可得出三种染色体核型：小叶锦鸡儿的染色体数为2n = 16 ，其核型公式为2n = 16 = 16m ( 4sat ) ；中间锦鸡儿的染色体数为2n = 18 ，其核型公式为2n = 18 = 16m ( 4sat ) + 2m ；树锦鸡儿的染色体数为2n = 20 ，其核型公式为2n = 20 = 20m ( 4sat ) ，结合形态学所得结论，可推测：中间锦鸡儿为小叶锦鸡儿和树锦鸡儿的中间类型或杂交种，也可能是具有递增染色体基数的不同种。
