nondisjunction

nondisjunction

1. Nondisjunction of chromosome 21 is much more frequent than loss in vivo and in vitro.No significant difference in nondisjunction between male and female was noted.

21号染色体不分离与年龄的关系极显著，无论在体内还是体外，21号染色体不分离远远高于丢失。

2. Y chromosomal nondisjunction

Y染色体不分离

3. nondisjunction gate

“或非”门

4. nondisjunction mosaic

不离开嵌合体

5. Alternatively, like allopolyploids, they may arise by the nondisjunction of chromatids during the mitotic division of a zygote.

与异源多倍体相似的是，它们也是在有丝分裂中合子的染色单体不分离形成的。

6. secondary nondisjunction

二次不离开 次级不离开

7. meiotic nondisjunction

减数分裂不分离

8. primary nondisjunction

初次不分离

9. See nondisjunction.

参见nondisjunction。

10. reverse nondisjunction

反转不分离

11. postzygotic nondisjunction

合子后(染色体)不分离

12. Autopoly-ploids may arise from the fusion of diploid gametes that have resulted from the NONDISJUNCTION of chromosomes at meiosis.

同源多倍体通常可能来自在减数分裂过程中染色体不分离导致的二倍体融合。

13. equational nondisjunction

均等不离开

14. partial nondisjunction

局部不离开

15. mitotic nondisjunction

有丝分裂不分离

16. chromosomal nondisjunction

染色体不分离

17. Keywords chromosome nondisjunction;Down syndrome;parental origin;

染色体不分离;先天愚型;双亲起源;

18. chromatid nondisjunction

染色单体不离开

19. nondisjunction decomposition

相交分解

20. dumpy sub-loci nondisjunction

矮胖亚位点不分离

21. first division nondisjunction

第一次[减数]分裂不分离

22. cytological numerical nondisjunction

细胞(数量)不分离

23. cytological nondisjunction

细胞的(数量)不离开

24. Results 64% of oocytes were normal, 36% of oocytes were aneuploidy, of which 22% were due to nondisjunction and 14% unbalanced predivision.

结果64%的卵细胞核型正常,36%的卵细胞为非整倍体,其中22%为同源染色体不分离,14%为姐妹染色单体非平衡性过早分离。

25. genetical nondisjunction

遗传不分离

26. genetic nondisjunction

遗传不分离作用

27. Aneuploidy The condition, resulting from nondisjunction of homologous chromosomes at meiosis, in which one or more chromosomes are missing from or added to the normal somatic chromosome number.

非整倍性：在减数分裂的过程中同源染色体不分离而造成的一条或多条染色体的缺失或增加。
