chromosome deletion

2 cases of Y chromosome deletion ;

缺失Y染色体12例；

Chromosome deletion was observed in some cells of haploid or double haploid plants .

观察到再生株中个别细胞染色体的丢失现象。

The derivative chromosomes resulted from unbalanced translocations , most of which were missed as chromosome deletion , additional material of unknown origin , monosomy and marker chromosome .

后者均系不平衡易位所致，其中不少被CC误认为染色体部分缺失、不明来源的额外物质、染色体单体和标记染色体等。

Objective : To investigate the relation between Y chromosome deletion and idiopathic azoospermia , severe oligozoospermia ; and investigate variability of Y chromosome deletion situs and rate in the nations .

目的：研究Y染色体基因微缺失与特发性无精子症和严重少精子症的关系，及探讨Y染色体基因微缺失的位点、缺失率有无民族间的差异性。

Chromosome deletion was triggered by Cre / loxP-mediated inverse sister chromatid recombination in the G2 / M phase of the cell cycle , leading to the generation of daughter cells missing part of or the entire recombinant chromosome .

在细胞有丝分裂的G2/M期，Cre/loxP介导的反向染色单体重组可以导致染色体删除，分裂后产生的子细胞将丢失全部或者部分的重组染色体。
