Question

Meiosis involves

• A. Two nuclear divisions and one chromosome division
• B. One nuclear division and one chromosome division
• C. One nuclear division and two chromosome divisions
• D. Two nuclear divisions and two chromosome divisions

Answer 1

The correct option is A Two nuclear divisions and one chromosome division

Meiosis is the cell division which results in the formation of four haploid cells from the diploid parent cell. There are two phases, meiosis I and meiosis II. The nuclear division occurs twice. There is a breaking of the chromosomes only in the anaphase II of meiosis II. In meiosis I, there is a separation of chromosomes towards opposite pole without breaking of the centromere. Thus, the correct answer is option A.
