Question

The formation of recombination nodules and terminalisation occur respectively during :

Answer 1

Answer:

Prophase 1 of meiosis

Recombination nodules are seen in pachytene

Terminalization occurs in Diakinesis

Explanation:

Prophase is the longest phase of karyokinesis of meiosis and it is divided into 5 phases. Leptotene is the stage where the chromosome appears as a long thread with chromosomes on it. Then we have zygotene where bivalents or tetrads are seen are seen. Pachytene is the state where the crossing over and the formation of recombinant nodules takes place. Diplotene is a stage where the chiasmata and the X-shaped structure are seen. Diakinesis is the where terminalisation takes place.

Answer 2

Pachytene and diakinesis

Reason

Pachytene is the state where the crossing over and the formation of recombinant nodules take place .

Diakinesis is the place where terminalisation of chiasmata take place.
