Each cell contains 23 pairs of chromosomes - a total of 46.
If an organism has too many chromosomes (polyploidy), it can disrupt normal development and lead to genetic disorders or even be fatal. If an organism has too few chromosomes (aneuploidy), it can also cause developmental abnormalities, reproductive issues, and health problems. Both situations can lead to infertility or decreased viability of the organism.
Condensation and shortening of chromosomes occur during the prophase stage of mitosis. In prophase, the chromatin fibers condense and coil tightly to form distinct, visible chromosomes.
Chromosomes align on the spindle equator during the metaphase. During the metaphase the chromosomes meet on an imaginary line between the two poles.
No, chromosomes do not double in mitosis. Instead, the existing chromosomes are replicated during the S phase of the cell cycle, resulting in two identical sister chromatids for each chromosome. During mitosis, these sister chromatids are separated to form two new daughter cells with the same number of chromosomes as the parent cell.
