Q. Match the stages of meiosis in column I to their characteristic feature in column II and select the correct option using the codes given below: [table] Column-I | Column-II ; a. Pachytene | i. Pairing of homologous chromosomes ; b. Metaphase I | ii. Terminalisation of chiasmata ; c. Diakinesis | iii. Crossing over takes place ; d. Zygotene | iv. Chromosomes align at equatorial plate [/table]
A) (a)-(iii), (b)-(iv), (c)-(ii), (d)-(i)
B) (a)-(i), (b)-(iv), (c)-(ii), (d)-(iii)
C) (a)-(ii), (b)-(iv), (c)-(iii), (d)-(i)
D) (a)-(iv), (b)-(iii), (c)-(ii), (d)-(i)
Explanation
[Solution] Pachytene: crossing over; metaphase I: alignment at the equator; diakinesis: terminalisation; zygotene: pairing (synapsis). Answer (1).
