染色体

Understand the chromosomal basis of inheritance and sex-linked genes.

了解染色体是遗传的基础以及性染色体的遗传模式。

In dogs, CA is also usually an autosomal recessive gene, but in a few breeds, such as the English Pointer, the gene is sex-linked.

在犬类中，小脑活力缺失通常是常染色体隐性基因遗传病，但在少数品种中，例如英国指示猎犬，该疾病由性染色体连锁遗传。

Topics include DNA and chromosomes, population genetics, immunity and cancer, genetics technology, sex-linked diseases, Mendel's Laws, and gene mutation.

这些主题包括DNA和染色体、群体遗传学、免疫和癌症、遗传学技术、性染色体疾病、孟德尔原理、以及基因突变。

Based on the number of families with at least one affected girl and the number of patients per sibship among these pedigrees, the proportion of families with DMD inherited as an AR trait was estimated.

结果：常染色体隐性遗传的类DMD患者独立行走的平均时间为（1.47±1.00）岁，症状出现的平均时间为（8.11±4.32）岁，血清肌酸激酶平均水平为（2785.10±1500.29）U/L，这种常染色体隐性遗传型类DMD占DMD的9.4%。

Results Stable Spectral Karytyping method was set up and extraordinary multiplicity of structure, including metathesis、depletion、amplification、rearrangement、equiarm、marker-body and so on were found by this methad.

结果 我们建立了稳定的光谱核型分析方法，发现肿瘤实体瘤染色体异常呈多倍体且结构异常复杂，包括易位、缺失、扩增、重排、双着丝粒、等臂及标记染色体等。

If an intestinal cell in a grasshopper contains 24 chromosomes,a grasshopper sperm cell would contain ___ chromosomes.

如果一只蚱蜢的肠细胞有24个染色体，那他的精细胞有几条染色体？

RSB-66 was obtained from the SSH library of round spermatid-specific cDNAs against those of primary spermatocyte.

尽管FcαRI也是一种免疫球蛋白的Fc受体，但是它却和其它免疫球蛋白的受体有很大的不同，其它免疫球蛋白的FcRs大都定位在1号染色体的q21-23，上，而FcαRI却定位在19号染色体的q13.4，这个区域因为定位了几个包括杀伤细胞抑制受体和白细胞Ig样受体的白细胞受体家族而被称为

In present study, we microisolated several X chromosomes of spiny eel and constructed a X chromosome library.

因此，本研究利用显微分离技术，对刺鳅的性染色体实现了显微分离并建立了X染色体涂绘文库。

The results showed that, under P sufficient conditions, 2 QTL were identified for SPUE on chromosome 1B and 5A, respectively; 3 QTL were detected on chromosome 2B, 5A and 7A, respectively, influencing WPUE. Under P deficient conditions, 3 QTL on chromosome 2D, 3B, and 6D were detected for SPUE, and 2 QTL on chromosome 2D and 7A for WPUE.

结果表明，正常供磷，有2个与SPUE有关的QTL，分别位於染色体1B和5A上，变异解释分别为6.55%和11.61%；与WPUE有关的QTL有位於染色体2B、5A和7A上的3个；SPUE和WPUE还分别受一对互作位点的影响。

The stereographical examination of surface spread chromosomes revealed that stretched chromosomes were composed of a mass of twisted looping fibers with an average diameter of about 300 A.

在染色质纤维未完全展开排列紧密时，染色体臂的染色质纤维，缠绕排列有序，垂直于染色体纵轴，螺旋盘绕形成疏密程度不同的横纹。

I am accused of being overreligious," she said in her quiet, frank manner,"but that does not prevent me thinking the children very cruel who obstinately commit such suicide.""

客人们在卡罗利娜·埃凯家里，举止就文雅一些，因为卡罗利娜的母亲治家很严厉。
