Question

Identify the correct matched pair :-

• A. Centromeric division in meiosis − Anaphase-I
• B. Exchange of genetic material – Pachytene
• C. Tetrad visibility in meiosis – Zygotene
• D. Terminalization in meiosis – pachytene

Answer 1

The correct option is B Exchange of genetic material – Pachytene

Exchange of genetic materials occurs in pachytene (Meiosis I of Prophase I of Pachytene sub-phase).

During meiosis, genetic information is exchanged between the maternally and paternally inherited copies of a pair of chromosomes in order to create new combinations of genes under the process of crossing over.

Tetrad visibility occurs in meiosis I of prophase I of pachytene.
Terminalisation in meiosis – Diakinesis.
Centromeric division occurs in Anaphase-II.

So, the correct answer is "option D"
