During meiosis I , in which stage synapsis takes place?
Options
- APachytene
- BZygotene
- CDiplotene
- DLeptotene
Correct answer
B. Zygotene
Step-by-step solution
Prophase I is subdivided into five phases, viz. Leptotene, Zygotene, Pachytene, Diplotene and Diakinesis. Leptotene: During this stage, the chromosomes become gradually visible under a light microscope. Compaction of chromosomes continues throughout this phase. Zygotene: Chromosomes start pairing together. This process is called synapsis. The paired chromosomes are called homologous chromosomes. The formation of synapsis is accompanied by the formation of the synaptonemal complex. Pachytene: Recombination nodules a
