To observ the toxicity of infected mice and establish mice reproductive toxicity model;②To observe the infected BALB/c female mice ovulation quantums and ovum chromosome;③To observe the oestrogenic hormone( FSH, LH, E2 )level of infected BALB/c female mice;④To observe zygote developmental condition before nidation;⑤To observe embryonic development condition of infected mid-gravidity mice to research the reproductive toxicity and development toxicity of toxoplasma gondii to the BALB/c female mice.

目的： 本实验采用弓形虫感染BALB/c雌鼠，①观察染虫雌鼠的毒性反应，建立生殖毒性的小鼠模型；②染虫雌鼠排卵情况及卵母细胞染色体的变化；③染虫雌鼠性激素(FSH、LH、E2)水平的变化；④着床前受精卵的发育情况；⑤孕中期鼠染虫后胚胎的发育情况，探讨弓形虫对雌鼠生殖功能及胚胎发育的毒性作用。

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。

There is a significant increase with age in the number of micronuclei and missegregation. 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.

在不同年龄正常人外周血淋巴细胞中，微核数随年龄的增加而增加。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。

It also led to the discovery in 1916 by Calvin Bridges of the phenomenon of nondisjunction, in which a chromosome pair fails to segregate during meiosis.

伴性遗传又导致了不分离现象的发现，即在减数分裂中，染色体对不分离。

Aneuploidy is that cells or individuals possess abnormal chromosome number resulted by nondisjunction during cell division .

非整倍体指染色体分离异常所导致的染色体数目非整倍性改变所得到的细胞与个体。

We observe an event of Cd delaying reproduction and discuss the relation between the event and X chromosome delaying reproduction as well as chromosomeal nondisjunction.

在本研究中，我们观察到某些染色体存在Cd迟滞复制现象，并对此作了讨论。

Two QTL for NSC translocation rate were identified on chromosome 12 and accounted for 8% and 14%, respectively, of the total variation.
