Question

Match the stages of meiosis in column I to their characteristic features in column II and select the correct option using the codes given below.

	Column I		Column II
A.	Pachytene	(i)	Pairing of homologous chromosomes
B.	Metaphase I	(ii)	Terminalisation of chiasmata
C.	Diakinesis	(iii)	Crossing­over takes place
D.	Zygotene	(iv)	Chromosomes align at equatorial plate

(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)

Answer 1

Ans : (1) (iii), (iv), (ii), (i) 

Explanation : 

Various phases of meiosis and their characteristic features are 

Pachytene  - Crossing-over takes place Metaphase-I  - Chromosomes align at equatorial plate 

Diakinesis - Terminalisation of chiasmata Zygotene - Pairing of homologous chromosomes
