n.偶（合）线期

The zygotene stage is the initial phase of prophase I in meiosis, where homologous chromosomes begin to pair up.
偶线期是减数分裂第一次成熟前期的初始阶段，同源染色体开始配对。
During zygotene, the synaptonemal complex starts to form between homologous chromosomes, facilitating their close association.
在偶线期，同源染色体之间开始形成合成络蛋白复合体，促进它们之间的紧密关联。
In zygotene, crossing over does not occur yet, but the homologous chromosomes start to exchange genetic material through a process called synapsis.
在偶线期，交叉互换尚未发生，但同源染色体开始通过一个称为配对的过程交换遗传物质。
The zygotene stage is characterized by the formation of a structure known as the synaptonemal complex, which holds homologous chromosomes together.
偶线期的特点是形成一种称为合成络蛋白复合体的结构，它将同源染色体结合在一起。
During zygotene, the pairing of homologous chromosomes is crucial for the proper segregation of genetic material during later stages of meiosis.
在偶线期，同源染色体的配对对于后期减数分裂过程中遗传物质的正确分离至关重要。
The zygotene stage is also significant for the repair of DNA damages that may have occurred during the previous cell cycle.
偶线期对于修复前一细胞周期中可能发生的DNA损伤也具有重要意义。
In zygotene, the initiation of recombination between homologous chromosomes marks the beginning of genetic diversity in the offspring.
在偶线期，同源染色体间的重组启动标志着后代遗传多样性开始。
The zygotene stage is often studied in model organisms like mice and fruit flies to understand the mechanisms of genetic recombination.
偶线期在小鼠和果蝇等模式生物中经常被研究，以了解遗传重组的机制。
During zygotene, the homologous chromosomes undergo extensive structural changes, including the condensation of chromatin and the formation of chiasmata.
在偶线期，同源染色体经历广泛的结构变化，包括染色质的凝缩和交叉区的形成。
The study of zygotene in humans can provide insights into genetic disorders and infertility issues related to meiotic abnormalities.
对人类偶线期的研究可以提供关于与减数分裂异常相关的遗传性疾病和不孕问题的见解。
