What is Diploid? – Meaning & Definition
Definition of Diploid
A diploid cell is a cell or an organism that contains two complete sets of chromosomes, one from each parent. This is represented as 2n in genetics.
Simple Meaning of Diploid
A diploid organism has two copies of each chromosome, one from the mother and one from the father.
Most animals and plants, including humans, have diploid cells in their body tissues (somatic cells).
Diploid cells are formed through mitosis, which ensures that each daughter cell has the same number of chromosomes as the parent cell.
Examples of Diploid Cells
Human Somatic Cells – 46 chromosomes (2 sets of 23)
Animal Body Cells – Found in skin, muscle, and liver
Plant Cells – Most plants have diploid cells in their tissues
Diploid vs. Haploid
| Feature | Diploid (2n) | Haploid (n) |
|---|---|---|
| Number of Chromosome Sets | 2 sets (from both parents) | 1 set (from one parent) |
| Examples | Body cells (skin, muscle, liver) | Gametes (sperm & egg) |
| Process of Formation | Mitosis | Meiosis |
| Human Chromosome Count | 46 (23 pairs) | 23 |
Importance of Diploid Cells
Maintain Genetic Stability – Ensures offspring receive genes from both parents
Cell Repair & Growth – Essential for body tissue development
Genetic Diversity – Helps in evolution and species survival

Here’s a clear explanation of the term Diploid, including its meaning, definition, and examples:
What is Diploid?
Definition:
A diploid cell or organism is one that contains two complete sets of chromosomes — one set inherited from each parent.
Meaning in Simple Words:
A diploid is a normal body cell that has two copies of each chromosome, just like humans have 46 chromosomes in total (23 pairs) — one from the mother and one from the father.
Scientific Definition:
A diploid (2n) cell contains two homologous sets of chromosomes, which means it has two chromosomes of each type, one from each parent.
Examples of Diploid Cells:
| Organism | Diploid Chromosome Number (2n) |
|---|---|
| Humans | 46 (23 pairs) |
| Dogs | 78 |
| Rice | 24 |
| Fruit fly | 8 |
In humans:
- Somatic (body) cells = diploid
- Gametes (sperm/egg) = haploid (contain only one set: n = 23)
Diploid vs. Haploid
| Term | Chromosome Sets | Found In |
|---|---|---|
| Diploid (2n) | Two sets (pairs) | Body cells (skin, blood, muscle) |
| Haploid (n) | One set | Gametes (sperm and egg) |
Importance of Diploid Cells:
- Maintain genetic stability from generation to generation.
- Allow for genetic variation through meiosis and fertilization.
- Help organisms grow and develop through mitotic division.
Summary
A diploid is any cell or organism that has two sets of chromosomes, one from each parent. This is the standard chromosome number in most animal and plant cells.
