Q. The given figure is the representation of a certain event at a particular stage of a type of cell division. Identify the stage and choose the correct option?

A) Prophase-I during meiosis
B) Prophase-II during meiosis
C) Prophase during meiosis
D) Both prophase and metaphase of mitosis
Explanation

Prophase-I is the longest stage in the first division of meiosis and is divided into a number of substages. The chronological sequence is leptotene, zygotene, pachytene, diplotene and diakinesis. The characteristic phenomenon during pachytene is the exchange of chromosomal segments, i.e., the recombination of gene or crossing over
