What is Diploid? (Meaning and Definition)
Diploid:
A diploid is a cell or an organism consisting of two sets of chromosomes — one set inherited from each parent. These cells have a pair of each chromosome (2n), making them essential for sexual reproduction.
Key Points:
- Symbol: Diploid cells are represented by 2n, where ‘n’ is the number of chromosomes in a single set.
- Examples: Most animal cells, including human body cells (somatic cells), are diploid with 46 chromosomes (23 pairs).
- Exception: Gametes (sperm and egg cells) are haploid (n) and contain only one set of chromosomes.
Diploid vs. Haploid:
- Diploid (2n): Two sets of chromosomes (body cells).
- Haploid (n): One set of chromosomes (sex cells or gametes).
Importance of Diploid Cells:
- They maintain genetic stability through mitosis.
- Facilitate genetic variation through meiosis and fertilization.
- Help in growth, development, and tissue repair.

What is Diploid? – Meaning and Definition
Definition:
A diploid cell or organism is one that contains two complete sets of chromosomes, one set from each parent.
Simplified Meaning:
A diploid has two copies of each chromosome — that means every gene is paired. It is written as 2n in biology.
Key Points:
Feature | Details |
---|---|
Chromosome number | Two sets (2n) |
Source | One set from mother, one from father |
Cell type | Somatic (body) cells |
Organism type | Most animals and plants |
Examples of Diploid Cells:
-
Human skin cells (2n = 46 chromosomes)
-
Liver cells
-
Muscle cells
-
Zygote (fertilized egg)
Important Note:
-
Diploid (2n) = Two sets of chromosomes
-
Haploid (n) = One set of chromosomes (e.g., sperm and egg cells)
In Simple Terms:
If a human has 46 chromosomes, 23 come from the mother, 23 from the father. That’s diploid — two sets!
Comparison: Diploid vs. Haploid
Feature | Diploid (2n) | Haploid (n) |
---|---|---|
No. of sets | 2 sets of chromosomes | 1 set of chromosomes |
Found in | Body cells (somatic) | Sex cells (gametes) |
Example | Blood cell, skin cell | Sperm, egg |
