In which stage of the cell cycle does a cell contain twice its normal number of chromosomes?

prophase I
metaphase I
anaphase I, although some may say that anaphase I is the point where the cell goes from 2n to n, which in turn will make the amount of DNA diploid, but this is truly based on how you rationalize and understand this.

Does the chromosome number changes throughout the human life cycle?
No a normal human will always have 46 chromosomes.
Why do chromosomes double during prophase?
When a cell divides, each of the daughter cells should contain a copy of the entire genome. This is the reason why a copy of every chromosome has to be made so that one half can go into each daughter cell. If the parent call contained 23 chromosomes for example, during the synthesis phase of the cell cycle (of which prophase is a part), the total number of chromosomes will increase to 46 since each chromosome will be copied. When the cell divides to create two daughter cells, each daughter cell will contain 23 chromosomes.
What might happen to a new cell if it didn't have the same amount of chromosomes as the original cell?
Then it's a prokaryote cell (such as bacteria). If not a prokaryote then it just wouldn't be a cell because with eukaryote cells, if there are no chromosomes, there is no cell or life with that cell.
What is the chromosome number of the parent cell in mitosis?
28
Why might Cells from an advanced malignant tumor most often have very abnormal chromosomes and often an abnormal total number of chromosomes?
Chromosomally abnormal cells can still go through cell cycle checkpoints.
Does the chromosome number changes throughout the human life cycle?
No a normal human will always have 46 chromosomes.
When during the human cycle is the diploid number of chromosomes restored?
Fertilization
Where in the cell cycle are chromosomes replicated?
The chromosomes are replicated during interphase.
Which stage of cells cycle do the chromosomes replicated?
Chromosomes replicate when DNA replicates during the S phase (synthesis) of of the cell cycle.

In a cells life cycle when to chromosomes duplicate?
Interphase
Which state is when the chromosomes are not visible in cell cycle?
Interphase
Why might Cells from an advanced malignant tumor most often have very abnormal chromosomes and often an abnormal total number of chromosomes?
Chromosomally abnormal cells can still go through cell cycle checkpoints.
What type of life cycle exists in which the haploid form?
The gametic life cycle exists in which the haploid form is always unicellular as in humans.
Which does not control the cell cycle?
The cell cycle is controlled by specific cyclins, which are proteins that regulate the cell cycle.
