Difference Between Haploid And Diploid (original) (raw)

Last Updated : 23 Jul, 2025

**Haploid and Diploid are two terms that represent the number of '"set of chromosomes" in a cell. **Haploid refers to the presence of a single set of chromosomes in an organism's cells while **Diploid refers to the presence of two sets of chromosomes in a cell. The term "PLOIDY" refers to the number of sets of chromosomes in a cell, hence the single set of chromosomes called **Haploid and the double set of chromosomes called **Diploid.

Definition of Haploid and Diploid

**Haploid describes a cell that contains a single set of chromosomes and Diploid is a term that refers to the presence of two complete sets of chromosomes in an organism's cells, with each parent contributing a chromosome to each pair.

Difference Between Haploid and Diploid

Following are the difference between haploid and diploid are given below:

Features HAPLOID DIPLOID
**Number of Chromosomes Sets Single set of chromosome Double sets of chromosome
**Process of Formation Meiosis (number of set of chromosomes halved) Mitosis (hence, no reduction of chromosome sets)
**Types of cell Mostly germ cells Mostly somatic cells
**Mutation Rate Lower than Diploids as they have half the number of nucleotide sites (and so, less amount of mutation) Higher than Haploids as double the number of nucleotide sites (with the ability to mutate)
**Types of Eggs Developed from unfertilized eggs. Developed from fertilized eggs.
**Similarity with Parents Genetically not similar to parents (due to crossing over ) Genetically identical to parents (due to mitosis process)
**Importance Vital for sexual reproduction and diversity of genetics. Vital for growth and development of organisms.
**Organisms Male ants and wasps Humans, frogs and most plants
**Example Human germ cells like ova and sperm cells Human cells like Skin cells and Muscle cells.

What is Haploid Cell ?

Haploid describes a cell that contains a single set of chromosomes. The term haploid can also refer to the number of chromosomes in egg or sperm cells, which are also called gametes. Represented by 'n' .In humans, gametes are haploid cells that contain 23 chromosomes, each of which a one of a chromosome pair that exists in diplod cells. The number of chromosomes in a single set is represented as n, which is also called the haploid number. In humans, n = 23.

What is Diploid Cell?

Diploid is a term that refers to the presence of two complete sets of chromosomes in an organism’s cells, with each parent contributing a chromosome to each pair. Represented by '2n'. Most cells in humans are diploid, comprising 23 chromosome pairs, so 46 chromosomes in total. Most mammals are diploid, like humans, but some organisms are polyploid, meaning they have more than two sets of each chromosome. For example, your standard grocery store strawberry is octoploid, with eight complete sets of seven chromosomes each, or 56 chromosomes in total.
