Given below is the representation of a certain event at a particular stage of a type of cell division. Which is this stage

A

Prophase-I during meiosis

B

Prophase -II during meiosis

C

Prophase of mitosis

D

Both prophase and metaphase of mitosis

Text Solution

Verified by Experts

The correct Answer is:
A
During zygotene stage of prophase-I of meiosis-I, bivalent chromosomes clearly appear as tetrads. Pachytene stage is characterised by the appearance of recombination nodules, the sites at which crossing over (exchange of genetic material) occurs between non-sister chromatids of the homologous chromosomes.
