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:

  1. Symbol: Diploid cells are represented by 2n, where ‘n’ is the number of chromosomes in a single set.
  2. Examples: Most animal cells, including human body cells (somatic cells), are diploid with 46 chromosomes (23 pairs).
  3. Exception: Gametes (sperm and egg cells) are haploid (n) and contain only one set of chromosomes.

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:


Important Note:


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
