(ploy'dē)
The number of haploid sets in a cell. Gametes normally contain one; autosomal cells, two.

ploidy

The number of copies of the set of chromosomes in a cell. A normal diploid cell with two copies has a ploidy of two; a haploid cell with one copy, such as an ovum or a spermatozoon, has a ploidy of one.

ploidy

the number of chromosome sets making up the total genome of an organism.

Thus the ploidy of normal humans is two and is written 2n. See DIPLOID (1).
