Meiosis is also alled reductional division because it halves the chromosome number in the daughter cells than those in the parental cell. It is so as the parental cell divides twice, while the chromosomes duplicate only once. Mciosis is of three types on the basis of period and site of occurrence of metosis.

Give its significance, (in) State one difference between gametic meiosis and zygotic meiosis.
