In humans, n = 23. Gametes contain half the chromosomes contained in normal diploid cells of the body, which are also known as somatic cells. Haploid gametes are produced during meiosis, which is a type of cell division that reduces the number of chromosomes in a parent diploid cell by half.
Which cells in an organism are diploid?
Diploid is a cell or organism that has paired chromosomes, one from each parent. In humans, cells other than human sex cells, are diploid and have 23 pairs of chromosomes. Human sex cells (egg and sperm cells) contain a single set of chromosomes and are known as haploid.
What is the diploid chromosome number of this organism?
For humans, the diploid chromosome number equation is 2n = 46 because humans have two sets of 23 chromosomes (22 sets of two autosomal or non-sex chromosomes and one set of two sex chromosomes).

What is an organism or cell with two sets of chromosomes?
Sexually reproducing organisms are diploid (having two sets of chromosomes, one from each parent). In humans, only their egg and sperm cells are haploid.
What are two examples of diploid cells?
A diploid cell contains two complete sets of chromosomes in its nucleus, whereas haploid cells only contain a single copy. Most human body cells are diploid, and only the gametes (sperm and egg cells) are haploid.
Examples of diploid cells in humans include:
- Muscle cells.
- Skin cells.
- Blood cells.
- Nerve cells.
- Bone cells.
What is meant by diploid cell?
Diploid describes a cell that contain two copies of each chromosome. … The total number of chromosomes in diploid cells is described as 2n, which is twice the number of chromosomes in a haploid cell (n).
How diploid cells are formed?
Diploid cells, or somatic cells, contain two complete copies of each chromosome within the cell nucleus. The diploid number of a cell is commonly abbreviated to 2n, where n is the number of chromosomes. … Diploid cells are produced by mitosis and the daughter cells are exact replicas of the parent cell.
What is diploid somatic cell?
A somatic cell is any cell of the body except sperm and egg cells. Somatic cells are diploid, meaning that they contain two sets of chromosomes, one inherited from each parent.
What is haploid cell and diploid cells?
Haploid cells are those that have only a single set of chromosomes while diploid cells have two sets of chromosomes.
Does mitosis have half the number of chromosomes?
Mitosis is a fundamental process for life. During mitosis, a cell duplicates all of its contents, including its chromosomes, and splits to form two identical daughter cells. … It is a two-step process that reduces the chromosome number by half—from 46 to 23—to form sperm and egg cells.
