Diploid
Diploid
Diploid (/ˈdɪplɔɪd/; from the Greek διπλοος, diploos, meaning "double") is a term in genetics referring to cells or organisms that have two sets of chromosomes.
Etymology
The term "diploid" comes from the Greek word "διπλοος" (diploos), meaning "double". It was first used in the late 19th century to describe organisms with two sets of chromosomes.
Definition
In a diploid state, the genome—the complete set of genetic material—consists of two copies of each chromosome, one from each parent. This is the normal condition for most animals and plants. In humans, for example, there are 46 chromosomes: 23 from the mother and 23 from the father, making humans diploid organisms.
