Meiosis I | Prophase - Leptotene | Zygotene | Pachytene | Diplotene | Diakinesis

Meiosis-prophase 1-leptotene | | Zygotene | | Pachytene | | Diplotene | | Diakinesis stage

Prophase of the first meiotic division is typically longer on complex. It is subdivided into 5 phases , leptotene, zygotene, pachytene,diplotene and diakinesis. Which of the following statements is not correct of these phases ?

Select the corret matches (a) S-phase - DNA replication (b) Zygotene - Synapsis (c) Diplotene - Crossing over (d) Meiosis - Both haploid and diploid cells (e) Gap 2 phase - Quiescent stage

Prophase of meiosis includes I. Leptotene II. Pachytene III. Cytokinesis IV. Kayokinesis Choose the option with correct statement(s).

In which phase of meiosis are the following formed ? Choose the answers from hint points given below. (a) Synaptonemal complex ..... (b) Recombination nodules .... (c) Appearance/activation of enzyme recombinase.... (d) Termination of chiasmata.... (e) Interkinesis.... (f) formation of dyad of cells.... Hint (a) Zygotene, (b) Pachytene, (c) Pachytene, (d) Diakinesis, (e) After Telophase-I/before prophase of meosis-II, (f) Telophase-I/after meiosis-I

Terminalisation is completed in diplotene/ diakinesis.

Synaptonemal complex appears in Leptotene/zygotene and disappears in pachytene/diplotene.

Assertion: The final stage of meiotic prophase I is diplotene. Reason: Diplotene is marked by terminalisation of chaisamata.
