The control gene for chromosome segregation existed in the P genome of Agropyron, thus causing formation of functional gamete and self-fertility of the hybrids involving Agropyron

冰草属的P染色体组存在染色体分离的控制基因，从而引起含有冰草属的杂种能够形成有功能的配子且自交可育。

F1 hybrid has the morphological feature which is between the male and female parents and shoed strong heterosis, exuberant vitality, late ripe period and low rate of self-fertility. The average chromosome configuration of F1 in PMC MI was 18.58Ⅰ+18.59Ⅱ+0.085Ⅲ+0.028Ⅳ. At anphase Ⅰ in PMC, some laggard chromosomes arranged in equatorial plate. Micronucleus and a lot of abnormal cells can be observed at dyad, tetrad and microspore.

杂种F1形态特征介于双亲之间，具有较强的杂种优势，生长旺盛，熟期晚，自交结实率较低。F1花粉母细胞减数分裂中期Ⅰ平均染色体构型为18.58Ⅰ+18.59Ⅱ+0.085Ⅲ+0.028Ⅳ，PMC后期Ⅰ观察到部分落后染色体排列在赤道板上；二分体、四分体和小孢子时期，细胞内普遍观察到微核，且出现大量异形细胞。

NEW YORK - Men and women with sex chromosome abnormalities are able to complete high school, hold full-time jobs, marry and have children, according to a new report.

Experiment result shows that 1.there are totally 26 chromosomes;2.chromosome 1,2,5,7,8,10,12 have central centromeres;chromosome3,4,6,9,11,13 have vise central centromeres;sex chromosome cannot be detected.

实验结果显示，其染色体共有2n=26条，其中其中1，2，5，7，8，10，12为中部着丝粒；3，4，6，9，11，13为亚中部着丝粒，性染色体无法分辨。

Here we show that a newly evolved sex chromosome contains genes that contribute to speciation in threespine stickleback fish.

基因定位研究显示，新形成的X染色体包含雄性求偶行为基因，而先祖X染色体既包含行为隔离基因，又包含杂交种雄性不育基因。

Because man can only inherit genes carried on the sex chromosomes while woman have 2 sex chromosomes, even if one of sex chromosome has defect, there is another one can take place for.

这是因为男人只能继承母亲身上一个X染色体的基因。而女人有2个X染色体，即使一个辨色基因出现缺陷，还有另一个基因可以顶替它的位置。

Although several genetic models has been proposed including autosomal-dominant/autosomal recessive, sex-linked, sex-limited, mitochondrial, and multi-gene, none of these models can well-explain the transmission of the disease.

尽管此前已提出包括常染色体显性/常染色体隐性，伴性性状，限性性状，线粒体性及多基因性遗传模式，但均难以很好地解释该病的遗传性。
