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.


Word origin: from Greek diplous, double + -OID

every plant has the gametophyte, the haploid stage that gives rise to gametes, and the sporophyte, the diploid stage that gives rise to spores. In mosses, the actual plant that you see is the gamethophyte, whereas the sporophyte is just the thing that looks somewhat like a ...
