Consider as what recessive heredity causes euchromosome to high myopia. 对于高度近视则认为是常染色体隐性遗传引起的。
Karyotype was conducted mainly by G banding. Results In 1097 cases of chromosome aberrance, the rate of abnormal euchromosome number and abnormal euchromosome structure was 1.73% ( 19/ 1097) and 13.49% ( 148/ 1097). 结果1097例染色体异常核型中,常染色体数目异常占1.73%(19/1097);常染色体结构异常13.49%(148/1097);
Results: The results showed 47 cases had abnormal chromosome, accounting for 8 4% of the total cases. Among them there were 39 cases of abnormal euchromosome, 8 cases of abnormal sex chromosome. 结果:发现47例染色体结构或数目异常,占受检人数的8.4%,其中常染色体异常39例,性染色体异常8例。
Conclusions FH is an euchromosome dominant genetic disease that is caused by the defective LDLR resulted from gene mutation. 结论:FH是一常染色体显性遗传性疾病,为基因突变导致LDLR缺陷所致的遗传性疾病。
By using two color FISH with one euchromosome probe and one sex chromosome probe, the sperm with same color of two hybridization signals in one sperm head could be identified as aneuploidy sperm or diploid sperm. 若用1条常染色体探针和1条性染色体探针进行FISH,可以区别头部有2个相同颜色荧光杂交信号的精子属非整倍体精子或二倍体精子。
Among these karyotype, 263 cases were euchromosome malformation, 194 were sex chromosome malformation. 染色体异常中常染色体异常263例,性染色体异常194例;
Sperm protein 22 ( sperm protein 22, SP22) is encoded by housekeeping gene of euchromosome. 精子蛋白22(Spermprotein22,SP22)是一种由常染色体的持家基因编码的蛋白。
Methods: Using site-specific primers for 24 euchromosome STR loci, the individual genome DNA of 66 cases of diad paternity testing were typed after synchronized PCR and PAGE followed by silver staining. 方法:应用PCR同步扩增24个常染色体STR基因座,PAGE电泳分型,完成二联体亲子鉴定66例。
It was proved that the plumage color gene h which control the black feather traits loci in the euchromosome, relative to allele H, is not completely recessive and the gene interact with B/ b and Y/ y loci in the Z-chromosome. 试验表明,控制黑羽性状的基因h位于常染色体上,相对于等位基因H为不完全隐性,该基因座与性染色体Z上的基因座B/b和Y/y具有一定的互作关系。
