Match the following stages during Prophase I with their key changes:
Column IColumn IIi. Leptotenea. Bivalents separate and remain attached at Chiasmata.ii. Zygoteneb. Pairing of opposite chromosomes.iii. Pachytenec.Bivalents divide and remain attached at Chiasmata.iv. Diplotened. Bivalents are formed and crossing over is seen.v. Diakinesise. Chromosomes are formed and in condensed stage.
i).➡ b., ii).➡ c., iii).➡ d., iv). ➡ e., v). ➡ a.
The correctly matched pairs of phases in Prophase I division with their key changes are:
(e) As chromosomes are formed and are in condensed stage it is ⇛ i). Leptotene,
(b) As pairing of opposite chromosomes appear, it is ⇛ ii). Zygotene,
(d) As bivalents are formed and crossing over is seen it is ⇛ iii). Pachytene,
(c) As bivalents divide and remain attached at Chiasmata it is ⇛ iv). Diplotene and
(a) As bivalents are separate and has a part of Chiasma it is ⇛v). Diakinesis.
So the correct options are as follows. -- v).→ a., ii).→ b., iv).→ c., iii). → d., i). → e.
