If we use the word "chromatid", there are always two. (As with twins!)
In a eukaryotic cell immediately after cell division (mitosis or meiosis), each chromosome contains only one DNA molecule.
If the cell is preparing for a subsequent division, then midway through interphase the DNA replicates. Now there are two molecules of DNA in each chromosome.
At the start of the following division, in prophase, the chromosomes condense, and the two DNA molecules, with their many associated proteins, become visible under a light microscope as sister-chromatids.

How many chromosomes does a tribbles body cells normally contain?
9 chromosomes
What do chromosomes contain that control the characteristic of the cells?
genes
What is the difference between a diploid cell and a haploid?
Diploid cells contain 2 sets of chromosomes, whereas haploid cells contain half of this (one set of chromosomes).
What type of cells contain only one set of chromosomes instead of two?
Gametes, also called sex cells, or sperm and egg cells, contain only one set of chromosomes.
Do you body cells of humans have 46 pairs of chromosomes?
A cell that contains both copies of each chromosome is called a Diploid cell.
What cell types contains the least number of chromosomes?
Sex cells contain half the number of chromosomes that body cells contain.
Through the process of meiosis sex cells are produced that are?
Haploid cells, as opposed to diploid cells. Haploid cells contain only 23 chromosomes, but normal diploid cells contain 46 chromosomes.
How many chromosomes does a tribbles body cells normally contain?
9 chromosomes
How many single chromosomes do humans have in their body cells?
Human cells contain forty-six chromosomes each. An exception to this is gametes (oocytes and sperm), which contain twenty-three chromosomes each.
Does each egg and sperm cell contain a full set of 46 chromosomes?
No. These cells contain only half the number of chromosomes as the other cells of the body. Each egg and sperm cell contain only 23 chromosomes.
What do chromosomes contain that control the characteristic of the cells?
genes
Does somatic cells contain sex chromosomes?
Yes ,they do .
How many chromosomes do the sperm cells contain?
23
Differentiate between diploid and haploid cells.-?
Diploid cells contain 2 complete sets of chromosomes, one from each parent. an example would be somatic cells. Haploid cells are cells that contain 1 set of unpaired chromosomes of half the number of chromosomes as a somatic cell.
What is the difference between a diploid cell and a haploid?
Diploid cells contain 2 sets of chromosomes, whereas haploid cells contain half of this (one set of chromosomes).
Which cells contain only sex chromosomes?
Gamete Cells Novanet Swag
Where are the human cells with 46 chromosomes found?
In humans, the diploid number (or 2n) is 46. Somatic cells contain 2n number of chromosomes. Somatic cells are those that make up the body. Every cells that makes up every organ contains 2n number of chromosomes. Gametes (or sex cells) contain haploid (n) number of chromosomes
