查询词典 sex chromosome

Granulosus is further;2. In differentiation of closely relatedspecies, the changes in heterochromatin and pericentric inversions are key factors, this is wellnoted in the small chromosomes;3. A. mantzorum has well-differentiated XY type sex chromo-'.omes, the Y chromosome is mainly composed of euchromatin, but has strong C-band in themiddle of the long arm. It is suggested that the Y chromosome of A. mantzorum is in the-initial stage of sex chromosome differentiation.

结果表明：(1)四川湍蛙、理县湍蛙和棕点湍蛙之间的亲缘关系较近，而它们与棘皮湍蛙的亲缘关系较远；2）在近缘种的分化中，染色体结构异染色质的变化和臂间倒位是重要的因素之一，这在小型染色体上表现得尤为突出；四川湍蛙具有在形态上分化很明显的性染色体。C带分析表明，此性染色体主要由常染色质构成，但在其Y染色体的长臂上存在明显的中间C带，推测尚处于性染色体分化的初期阶段。

The number of the chromosomes in Henan large tail sheep is 2n=54, the karyotypes of male and female sheep are 54, XY and 54, XX, respectively. There are 26 pairs of autosomes and 1 pair of sex-chromosome. Among 26 pairs of autosomes, 3 pairs are metacentric chromosomes, 23 pairs are telocentric chromosomes. X chromosome is the biggest subtelocentric chromosome and Y chromosome is the smallest submetacentric chromosome.

河南大尾寒羊二倍体染色体数目为2n=54，公羊核型54，XY；母羊核型54，XX.27对染色体中包括26对常染色体和1对性染色体，常染色体中有3对为中着丝粒染色体，23对为端着丝粒染色体；性染色体中，X染色体为最大的端着丝粒染色体，Y染色体为最小的中着丝粒染色体。

研究特色主要体现在：一、以我国特有的动物毛冠鹿为材料，在染色体和DNA水平上研究毛冠鹿核型多态与性染色体关系，探索毛冠鹿性染色体发生和演变的机制。

These sequences possessed highly copy number in the genome and were named as RMX1-6 individually. When these sequences were hybridized to chromosomes of spiny eel, RMX6 was proved to be sex chromosome specific and it only located in heterochromatic regions.

在随机挑取的三百多个克隆中，分离得到了6个高度重复序列，它们在基因组中存在较高拷贝数，按照发现顺序分别命名为RMX1—6(Repetitive sequence inMicrodissected X chromosome)。

Heterotypic sex chromosome was investigated on the metaphase chromosome of half-smooth tongue-sole and homotypic sex chromosome were investigated on the metaphase chromosome of half-smooth tongue-sole.

将GFP报告基因通过脂质体介导的方法转入SFEC和HTLC中并成功地获得了表达，转化率为20%左右。

Suppression of recombination is the prerequisite for plant sex chromosome evolution from a pair of autosomes. Recombination suppression around the locus controlling sex determination results in sex chromosome degeneration and differentiation.

重组抑制是植物性染色体由常染色体进化而来的前提条件，性别决定位点区域发生的重组抑制使早期的性染色体发生了退化和分化。

The results are as follow:The diploid chromosome number of Taihe Silkies was 2n=78,the basic number of chromosome arms was AF=90 and the sex chromosome type was ZZ/ZW.According to the measured relative length,arm ratio and centromeric index,the first 10 pairs of macro-chromosomes are described as follows:No.1 ,9 and Z,W chromosomes were metacentrics,No.2,4,7 were submetacentrics,and No.3,6,8,10 were telocentrics.Studies on Taihe Silkies′ G-band showed that the first 10 pairs of macro-chromosomes can be divided into 29 zones and 190 bands.
