The reduction divisions occur only in the reproductive cells at the time of gamete formation.
By this process, four daughter cells are formed from the single parental cell and
the chromosome number in them (the daughter cells or gametes) is reduced to half (haploid).
The entire process of meiosis is separated into a sequence of steps similar to those of mitosis, but these stages are repeated twice.
1. First prophase - The prophase of first division is longer and profoundly modified. It is divided into following fives stages–leptotenne, zygoene, pachytene, diplotene and diakinesis.
Leptotene or leptonema stage – The leptotene stage initiates meiosis.
The meiotic cell or meiotic is comparatively large and possesses a large nucleus.
