Diploid

Definition

noun

(Science: genetics, cell biology)

A cell or an organism consisting of two sets of chromosomes: usually, one set from the mother and another set from the father. In a diploid state the haploid number is doubled, thus, this condition is also known as 2n.


adjective

Of or pertaining to a diploid, that is a cell or an organism with two sets of chromosomes.


Supplement

An example of a cell in a diploid state is a somatic cell. In humans, the somatic cells typically contain 46 chromosomes in contrast to human haploid gametes (egg and sperm cells) that have only 23 chromosomes.
