双线期（英語： diplotene ，又称diplonema），名称来自希腊语的“两条线”。 [10]:30 在该时期，联会复合体解体，同源染色体彼此略微分开。然而，每个二价的同源染色体在进行交叉互换的地方保持紧密结合。
What is Diplotene? - BYJU'S
Diplotene is the fourth stage of meiosis prophase-1 (a five-stage process). It is preceded by the crossing over in the pachytene stage. Diplotene stage is characterized by desynapsis and chiasmata formation.
Meiosis - Wikipedia
During the diplotene stage, also known as diplonema, from Greek words meaning "two threads", [18]: 30 the synaptonemal complex disassembles and homologous chromosomes separate from one another a little. However, the homologous chromosomes of each bivalent remain tightly bound at chiasmata, the regions where crossing-over occurred.
The organization, regulation, and biological functions of the ...
During diplotene, the SC starts to disassemble unevenly, and regions of homologous chromosomes desynapse. At diakinesis, chromosomes undergo remodeling and condensation, and homologs are mainly held together by chiasmata (the cytological correlates of COs) and centromere pairing.

diplotene stage- (diplotene phase, diplonema; Greek, diplonema = "two threads") meiotic stage seen during prophase I, the chromosomes separate from one another a small amount giving this appearance. In the developing human ovary, oocytes remain at the diplotene stage from fetal life through postnatal childhood, until puberty when the lutenizing ...

2022年6月9日 · Diplotene. Definition noun The late stage of prophase I of meiosis I in which homologous chromosome pairs begin to separate and move away from one another except at chiasmata. Supplement Meiosis is form of cell division that gives rise to genetically diverse sex cells or gametes. It is comprised to two successive nuclear divisions namely meiosis..

Meiosis is arrested at the diplotene stage, during which oocytes grow to a large size. Oocytes then resume meiosis in response to hormonal stimulation and complete the first meiotic division, with asymmetric cytokinesis (more...)

双线期（diplotene stage）： 染色体进一步缩短，联会复合体解体。同源染色体开始分离，使交换后的染色体之间出现交叉（chiasma）。一般认为，交叉是非姐妹染色单体之间发生了交换的表现，随着时间的推移，交叉点向末端移动的现象称为交叉端化。
2.3: Meiosis - Biology LibreTexts
2023年6月20日 · In meiosis, Prophase I is divided up into five visual stages, that are steps along a continuum of events. Leptotene, zygotene, pachytene, diplotene and diakinesis. From interphase, a cell enters leptotene as the nuclear material begins to condense into long visible threads (chromosomes).
