A duplication of the chromosomes is what must happen before meiosis can begin.
Interphase. The process of meiosis has many similarities to the process of mitosis: chromosomes replicate before the process begins, and shorten and thicken to look like the chromosomes at the beginning of mitosis (condensation).
Introphase
B. Cells must divide twice before meiosis is complete C. Cells produced after meiosis I are diploid. D. Cells produced after meiosis II are haploid.
Meiosis I should not produce haploid cells. They should be diploid because before meiosis I the diploid cell duplicated its DNA. It is only after Meiosis II that the four cells are haploid.

Introphase
before
Before mitosis and meiosis, DNA is loose in the form of chromatin, then it coils into chromosomes right before the mitosis and meiosis.
Inter-phase occurs before mitosis or meiosis.
Meiosis produces the sperm and egg cells needed for reproduction. Only cells in the ovaries or testes undergo meiosis.
they have to duplicate
They mate.
