What is Leptotene?

Leptotene is the first stage of meiosis prophase-1. Meiosis one is the reduction division of cells where chromosomes are halved in the daughter cells.

In the leptotene stage, chromosomes uncoil and become thread-like structures (leptos = thin threads). Chromomeres, the beads like structure can be seen.

Leptotene stage is also known as the bouquet stage due to the specific alignment of chromosomes in the nucleus. Chromosomes converge to one side of the nucleus towards the centrosome.

Duplication of centriole takes place and they move to opposite poles of the nucleus, where they undergo further duplication.

Leptotene is followed by the zygotene stage.
