- Each homologous chromosome group has three homologous chromosomes. 每个染色体小组均由三条同源染色体组成。
- Of or relating to a chromosome that is not paired or united with its homologous chromosome during synapsis. 单价染色体的属于或有关一种染色体的，在染色体结合过程中不与它的对等染色体配对或结合
- 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。
- It is involved in processes such as homologous chromosome pairing, sister chromatid adhesion and separation, and some of the regulation initiated during anaphase. 在细胞有丝分裂和减数分裂中, 着丝粒作为保证染色体正常分裂并分离到子细胞的结构和功能元件, 参与了同源染色体配对、姐妹染色单体黏合、分离及分裂后期启动的调控等。
- The failure of homologous chromosomes to pair during meiosis. 不联会在减数分裂期间同源染色体不联会成对
- The separation of homologous chromosomes during meiosis. 在减数分裂过程中同源染色体的分离.
- The added 6VS univalent suppresses wheat homologous chromosome pairing, leading to the increase of wheat univalent, which is also relative to the interaction between wheat genetic backgrounds. 单体附加的6VS抑制小麦染色体正常配对，造成单价体数量增加，但其影响程度还与小麦遗传背景的互作有关。
- Pairing of homologous chromosomes (synapsis) commences at one or several points on the chromosome and is clearly seen during PACHYTENE of meiosis I. 同源染色体两两成对平行靠拢，这一现象也称联会，联会发生在染色体的一点或多点上，可以在减数第一次分裂的粗线期观察到。
- Homologous chromosomes have chromomeres in identical places along their length. 同源染色体在相同的部位具有染色粒。
- If both of a pair of homologous chromosomes are missing, nullisomy results. 如果一对同源染色体都缺失了，称为缺体。
- Having the same alleles at a particular gene locus on homologous chromosomes. 纯合的在同源染色体上某一特定基因座有相同等位基因的
- In pachytene the paired homologous chromosomes contract.At this point each chromosome consists of a pair of chromatids and the two associated chromosomes are termed a tetrad. 在粗线期，配对的同源染色体缩短，这时每条染色体包括2个联合的染色体，每个染色体包括1对染色单体，即四分体。
- separation of homologous chromosome 同源染色体分离
- One pair of homologous chromosomes resulting from the division of a tetrad during meiosis. 二分体一对由四分体在成熟分裂过程中形成的同源染色体

- homologous chromosome substi-tution 同源染色体替代
- Mitosis homologous chromosome pairing 有丝分裂同源配对
- This non sequitur invalidates his argument. 他不根据前提推理因而论证无效。
