Solution:
The meiosis occurs in two steps meiosis-I and meiosis -II. In meiosis -I. There is segregation of homologous pairs, i.e. paired chromosomes get separated and go to different gametes. So, the number of chromosomes becomes half in the two cells produced in meiosis -I. This is the reason it is called as reduction division. Meiosis-II is simply mitotic division in which two daughter cells produced in meiosis -I under go mitosis, thus produce four haploid daughter cells.
