Chromosomes become duplicated during meiosis. This is the process of replicating sex cells, otherwise known as gametes. This is how humans create new sex cells for reproduction.
The phase of cell division when duplicated chromosomes first appear is called the prophase. In prophase, the chromatin condenses into visible chromosomes, and the nuclear envelope breaks down, allowing the chromosomes to be more clearly visible.
After your 46 chromosomes are duplicated, your cell will have a total of 92 chromatids.
Chromosomes are duplicated during interphase, specifically during the S phase of the cell cycle. Mitosis is the process of cell division where the duplicated chromosomes are separated into two daughter cells.

In metaphase of mitosis, the number of chromosomes is equal to the number of duplicated chromosomes. However, in metaphase 2 of meiosis, the number of chromosomes is half that of the duplicated chromosomes, since meiosis involves two rounds of cell division to produce haploid cells.

Chromosomes are duplicated during the S phase of the cell cycle in a process called DNA replication. This ensures that each daughter cell receives a complete set of genetic material during cell division.
my college bio proffessor told me that even though chromosomes are still in the duplicated state, the chromosomes are duplicated so technically they do have "23" chromosomes but they instead have 2 sets of it. these 2 sets are the same so they dont count as a "full" set of 46 chromosomes. :) hope this helps!!
During the G1 phase of the cell cycle, chromosomes are not yet duplicated and appear as a single line of chromosomes within the cell. This is before DNA replication occurs in the S phase and chromosomes are temporarily duplicated.
The five basic stages of mitosis are: interphase, prophase, metaphase, anaphase and telophase. In prophase, the genetic material in the nucleus condenses and the duplicated chromosomes become visible. The nucleolus disappears and the nuclear envelope begins to break down, spindle fibers also start extending from both poles of the cell. In metaphase, the duplicated chromosomes become aligned in the center of the cell, spindle fibers attach themselves to the centromere of the chromosomes. In anaphase, the stage of mitosis in which the duplicated sets of chromosomes separate and two identical groups move to opposite poles of the cell. in telophase, a nuclear membrane re-forms around each new group of chromosomes.
