In meiosis crossing over is initiated at
1. leptotene
2. Zygotene
3. diplotene
4. pachytene
Column I | Column II | ||
(a) | pachytene | (1) | pairing of homologous chromosomes |
(b) | metaphase I | (2) | terminalisation of chiasmata |
(c) | diakinesis | (3) | crossing-over takes place |
(d) | zygotene | (4) | chromosomes align at equatorial plate |
