$\begin{array}{ccc}& \text{List I}& \text{List II}\\ & \text{(Phase of meiosis)}& \text{(Event that occurs)}\\ 1& \text{Prophase I}& \text{Crossing over occurs}\\ 2& \text{Metaphase II}& \text{Sister chromatids migrate to opposite poles}\\ 3& \text{Anaphase I}& \text{Homologous chromosomes line up at equator in pairs}\end{array}$

• A. 1, 2 , 3 correct
• B. 1 correct
• C. 2, 3 correct
• D. 1, 3 correct

Answer 1

The correct option is B 1 correct

Phases of meiosis:

Prophase-I: This phase is divided into five substages - leptotene, zygotene, pachytene, diplotene and diakinesis.
Crossing over occurs in pachytene stage of prophase-I.

Metaphase-II: Chromosomes arrange on equator of cell to form second metaphasic plate.

Anaphase-I: Homologous chromosomes segregate from each other and move towards the opposite poles.
