Diplotene: meaning, definitions and examples
๐งฌ
diplotene
[ หdษชplษสหtiหn ]
cell division
Diplotene is a stage in the prophase of meiosis during which homologous chromosomes begin to separate but remain connected at points called chiasmata. It follows the pachytene stage and is characterized by the chromosomes becoming more visible as they condense, while the nuclear envelope remains intact. This phase is crucial for genetic recombination and the production of gametes.
Examples of usage
- During meiosis, cells progress through diplotene before moving to diakinesis.
- The process of crossing over occurs significantly during the diplotene stage.
- In plant biology, observing diplotene can help determine the fertility of pollen grains.

Word origin
The term 'diplotene' is derived from the Greek words 'diplous', meaning 'double', and 'tรชnรช', meaning 'stretch' or 'thread'. This reflects the nature of the chromosomes during this stage of meiotic division, where homologous chromosomes appear as paired, double-stranded structures. Diplotene is a recognized part of the meiotic process, which was first described in detail in the early 20th century as scientists began to develop a better understanding of cellular division. Meiosis, which includes the diplotene stage, is essential for sexual reproduction and has significant implications in genetics and evolution. The study of diplotene has also provided insights into chromosomal abnormalities and developments in various species, enhancing our understanding of genetic diversity.
