(A) Meiosis consists of two successive nuclear divisions: Meiosis-$I$ and Meiosis-$II$.Meiosis-$I$ is known as the reductional division because the chromosome number is reduced to half.Meiosis-$II$ is known as the equational division because the number of chromosomes remains the same as in the parent cell (similar to mitosis),as it involves the separation of sister chromatids.
