C. Meiosis :

The term meiosis was coined by J. B. Farmer in 1905.

It takes place only in reproductive cells during the formation of gametes.

By this division, the number of chromosomes is reduced to half, hence it is also called reductional division.

The cells in which meiosis take place are termed as meiocytes.

Meiosis produces four haploid daughter cells from a diploid parent cell. Meiosis is of two subtypes :

1. First meiotic division or Heterotypic division – (Meiosis I)

2. Second meiotic division or Homotypic division (Meiosis II)
