Cytogenetical studies were made on chromosome behavior in intergeneric hybrids of some plants of brassicaceae.
作者对芸苔族植物两个属间杂种的染色体行为作了观察 ,在芥蓝和诸葛菜属间杂种一代植株根尖细胞 ,观察到芥蓝染色体和诸葛菜染色体之间的形态差别及染色体行为不同步 。
4) chromosome genetic behavior
染色体遗传行为
5) Abnormal chromosomal behavior
染色体行为异常
1.
Abnormal chromosomal behavior of root tip cells emerged when the NaCl concentration was more than 100 mmol/L.
结果表明,随着NaCl浓度的升高,旱稻的发芽率、发芽指数、活力指数逐渐降低;NaCl浓度高于100 mmol/L时,引起根尖细胞染色体行为异常,异常类型有微核、多核、染色体落后、染色体粘连、染色体桥、染色体断裂等。
6) chromosomal abnormal behavior
染色体异常行为
1.
Observation of the variation of the chromosomal behavior in second Filial generation during meiosis is made on the hybrid of wheat -rye 5R/5A disomic substitution line and 6R/6A disomic substitution line, and the chromosomal abnormal behavior and the coherency with chromosomal translocation are analyzed.
所以,在减数分裂过程中出现单价体、多价体、落后染色体、微核等染色体异常行为,这些现象会影响染色体配对、交换,对研究染色体易位的形成能提供重要依据。

常染色体隐性遗传型少汗性外胚层发育不良综合征
本病为常染色体隐性遗传,但据观察其临床表现不能与X连锁遗传者相区别,自然病程也与之相似,只是臭鼻症(恶臭,化脓性鼻分泌物排出)更重。其父母均正常。
