We just divide it by 2 in order to find it. So 46 chromosomes/2 = 23 chromosomes

Answer:

23 chromosomes (46 total)

Step-by-step explanation:

During Interphase, the DNA is copied. Hence, there are 2 copies of one chromosome. This means that there are now 46 pairs of chromosome in the parent cell.

However, during cytokinesis, the cell divides itself into two, meaning that each daughter cell are left with 23 pairs of chromosomes or 46 chromosomes.

Thanks.

Definition(s):

Mitosis: The usual method of cell division, characterized typically by the resolving of the chromatin of the nucleus into a threadlike form, which condenses into chromosomes, each of which separates longitudinally into two parts, one part of each chromosome being retained in each of two new cells resulting from the original cell.

Cytokinesis: The division of the cell cytoplasm that usually follow mitotic or meiotic division of the nucleus.

Chromosomes: Any of several threadlike bodies, consisting of chromatin, that carry the genes in a linear order: the human species has 23 pairs, designated 1 to 22 in order of decreasing size and X and Y for the female and male sex chromosomes respectively.

Daughter cell: A cell produced by reproductive division of a cell during mitosis or meiosis.

Parent cell: A cell that is the source of other cells, such as a cell that divides to produce two or more daughter cells, or a stem cell that is a progenitor of other cells or is the first in a line of developing cell, is called a parent cell. It is sometimes also called the mother cell.
