And , notes Hughes, finding aneuploidy in one or two cells of an embryo does not always mean that the embryo will not be viable .

而且如 Hughes 指出的，从一个胚胎中发现 1 到 2 个非整倍性的细胞并不意味着胚胎就无法存活。

Chromosomal instability leads to a condition known as aneuploidy , in which chunks of DNA are either missing or duplicated .

染色体的不稳定就会导致非整倍体的发生，这样 DNA 的记忆单位就会丢失或重复。

4

Euploidy The normal state in which an organism's chromosome number is an exact multiple of the haploid number characteristic of the species .

正常状态下，生物体染色体数是此种生物单倍体数目整数倍的现象被称为整倍性。

5

An aneuploid state in which a third homologous chromosome is present in addition to the normal autosomal pair is called trisomy .

除了正常染色体对以外，还存在有第二种同源染色体的非整倍体状态，被称为三体性。

6

Early cancers could also be distinguished from morphologically identical benign tumors by checking for aneuploidy .

检测非整倍体的存在与否，也可区分早期的癌细胞与外型相同的良性肿瘤。

7

An exact multiple of the haploid number is called euploid .

确切的单倍体数目倍增被称为整倍体。

The observed chromosome number revealed that all of the hybrid offspring were diploid , but each strain had some aneuploid cells.

染色体数目观察结果表明：均为二倍体植株，但各株系还出现了一些非整倍体细胞；

17

Hence , precise detection of the over- or underrepresentation of sequences from an aneuploid chromosome could be more readily achieved.

由此，在非整倍体染色体中进行过度表达或表达不足序列的精确检测会更容易实现。

18

These findings suggest that carcinogens function as "aneuploidogens" rather than as mutagens .

这些发现显示：致癌物质的作用在于造成非整倍体，而非突变。

还就整倍体后代中出现新杂交带型的可能原因进行了讨论。

21

In fact , the cell colonies from the euploid cell nuclei populations were larger and more dense than those from the aneuploid ones.

事实上，整倍体的细胞核群体的细胞集落比那些非整倍体的细胞多而密集。

22

Aneuploidy is associated with cancer .

非整倍体与肿瘤相关。

23
