This case report allows a further delineation of the trisomy lq syndrome.

这个案例的报告将有助於我们对部分三染色体第一号症候群的了解。

The nasal bone was absent in 43 of 59 (73%) trisomy 21 fetuses and in three of 603 (0.5%) fetuses with normal karyotype.

在59名第21对染色体三体的胎儿中有43名(73%)出现了鼻骨缺失，在正常染色体组合的603名胎儿中有3名(0.5%)出现鼻骨缺失。

Besides, he also suffered from congenital hydrocephalus and hypogammaglobulinemia, which have not been described in trisomy lq syndrome.

除此之外，他还并发先天性水及及免疫球蛋白低下等两项以前在部分三染色体第一号症候群尚未被报告过的症状。

Orientale additional and substitutional lines. chromosome number of 96 BC2 F3 individuals were accounted. Fifteen plants with 2n= 43 and eight plants with 2n= 44 were checked out. GISH results of the individuals with 43 chromosomes showed that they blonged to three different monosomic additions. Two disomic additions, ine double-monosomic addition, one trible- monosomic addition and one monosomic addition were found in the 2n = 44 individuals. One double-monosomic substitution and one monosomic sustitution were obtained.

为了筛选小麦-旱麦草异附加系、异代换系，对普通小麦品种Fukuho×东方旱麦草属间杂种的BC2F3代材料的96粒种子进行了染色体数目的检测，共检出15粒2n=43的种子，8粒2n=44的种子，进一步对以上材料进行的基因组DNA原位杂交，共鉴定出3个单体附加系，2个二体附加系，1个双单体附加，1个小麦三体单体附加，1个附加3条东方旱麦草染色体的小麦单体，在染色体数为42的个体中，检测出1个单体代换，1个双单体代换。

With immature embryos of Citrus grandis'Guanximiyou' as material, the effect of the three factors, enzyme treating time, pycnosis treating time in ice water and dyeing, were studied in the process of single chromosome microdissection technique.

以'琯溪蜜柚'幼胚为材料，对单染色体微分离制片过程中酶解时间、冰水固缩时间和染色三因素的影响效果进行了研究。

Villosum to wheat using ph lb mutant, as well as the development, identification and cytogenetic characteristics of a trigeneric hybrid germplasm with useful genes from Tavestivum, D.villosum and S.cereale.

结果发现：仅在50μg/mlBrdu溶液20～21h的培养条件下，9.3％的黑麦根尖细胞染色体产生脆性位点表达，主要分布在三条黑麦染色体的四个不同位点上，频率分别为1.4％、2.1％、4.3％和5.7％。

And Pharaoh spoke to Joseph, saying, Your father and your brothers have come to you.
