Second, it is successful to try applying the dripping method of suspended cells obtained by enzyme treatment instead of traditional method for pachytene chromosomes preparation.

第二，改变普遍采用的粗线期染色体制备的传统方法，尝试用酶解滴片法制备了水稻减数分裂染色体，获得了成功。

This well prove that relative length of pachytene chromosomes was a stable data and it was more appropriate to act as a parameter to establish pattern on the condition of with same material.

用Image J染色体分析软件来测量家蚕粗线期染色体相对长度和绝对长度与传统的细铜丝测量相比，减少了步骤，降低了主观误差，大大提高了准确性和工作效率。2。

Pairing of homologous chromosomes commences at one or several points on the chromosome and is clearly seen during PACHYTENE of meiosis I.

同源染色体两两成对平行靠拢，这一现象也称联会，联会发生在染色体的一点或多点上，可以在减数第一次分裂的粗线期观察到。

Red CPD bands were shown on eight pachytene bivalents, and 12 bands were shown on six pairs of mitotic metaphase chromosomes.

CPD 染色在8条粗线期染色体上显示出了10条红色的CPD 带纹，在6对有丝分裂中期染色体上显示出了12条CPD带纹。

The CPD bands exhibited on mitotic metaphase chromosomes corresponded to the prominent bands exhibited on the pachytene chromosomes.

有丝分裂中期染色体上的CPD带纹与粗线期染色体上显要的带纹具有对应性。

The human Y chromosome is paternally inherited in a haplotype model.

人类Y染色体为正常男性特有、其大部分非重组区呈父系单倍型遗传等特点，使得Y染色体特异的多态性遗传标记成为人类学、群体遗传学及法。。。

This gene normally expresses from the paternally inherited chromosome and is an imprinted gene on chromosome 9 associated with post-natal growth, study author Tomohiro Kono, of the department of bioscience at Tokyo University of Agriculture, explained in a news release from the journal's publisher.

该基因可正常表达来自父系遗传的染色体，是和出生后生长相关的9号染色体上的一种印迹基因。

The human Y chromosome is paternally inherited in a haplotype model. This feature make the Y-specific polymorphic markers are very useful in different fields of science, including genealogy, population genetics and forensic science.

人类Y染色体为正常男性特有、其大部分非重组区呈父系单倍型遗传等特点，使得Y染色体特异的多态性遗传标记成为人类学、群体遗传学及法医学等领域中非常有用的工具。

Medication during early pregnancy can cause fetal spina bifida, cleft palate, clubfoot, small limbs, Phocomelia, umbilical prominent cheek transverse fissure, cerebral meningocele, cerebral spinal cord dysfunction, osteogenesis imperfecta and fetal death. 2, prednisone: big neat administration during early pregnancy can cause stillbirth, streaming, no brains infants, small ectopic kidney, one-eyed, cleft palate, bone deformities, such as. 3, 6-8 weeks pregnant villus chromosome examination; pregnant 16-20 weeks to do the amniotic fluid puncture in amniotic fluid cell chromosome examination; At the same time, dynamic observation of maternal alpha-fetoprotein content; attention fetal B-track general shape and structural abnormalities offal.

妊娠早期用药可致胎儿脊柱裂，腭裂，畸形足，小肢，短肢畸形，脐突出，颊横裂，脑脊膜膨出，脑脊髓功能障碍，成骨发育不全及胎儿死亡。2、强的松：妊娠早期大齐整给药可引起死产、流、无脑儿、小异位肾、独眼、腭裂、骨畸形等。3、孕6-8周取绒毛组织进行染色体检查；孕16-20周行羊水穿刺做羊水细胞的染色体检查；同时，动态观察母血中的甲胎蛋白含量；注意B超跟踪胎儿大体形态和内脏结构是否异常。

She gently rebuff ed him, but agreed that they could be friends

她婉言拒绝了，但同意作为朋友相处。

If in the penal farm, you were sure to be criticized.

要是在劳改农场，你等着挨绳子吧！
