非同源染色体

一段染色体跟非同源染色体连在一起时就发生易位。

Translocation occurs when a fragment of one chromosome becomes attached to a non-homologous chromosome .

初步认为，次级联会产生的原因是非同源染色体之间的同祖关系。赖草染色体组J、N可能来自同一原始染色体组X。

The result showed that the secondary assocition originated from homoeology between J and N possibly originated from same genome X.

此外，大白菜为小染色体物种，且非同源染色体形态相似。

In addition , the chromosome of Chinese cabbage is small , and the form nonhomologous chromosome is similar .

每一对同源染色体的G－带带型基本相似，非同源染色体间具有不同程度的差异。

Each of the two members of the chromosome pairs resembles each other and nonhomologous chromosomes are not the same in G-banding patterns .

易位的48.57%发生在小麦和黑麦的部分同源染色体之间，51.43%发生在非部分同源染色体之间。

48.57 % of the identified wheat / rye translocations occurred between homoeologous and 51.43 % between non-homoeologous chromosomes .
