tetraploid

 [tet´rah-ploid]
1. characterized by tetraploidy.
2. an individual or cell having four sets of chromosomes.

pol·y·ploi·dy

(pol'ē-ploy'dē),
The state of a cell nucleus containing three or more haploid sets. Cells containing three, four, five, or six multiples are referred to, respectively, as triploid, tetraploid, pentaploid, or hexaploid.

tetraploid (4n)

[tet′rəploid]
Etymology: Gk, tetraploos, fourfold, eidos, form
1 an individual, organism, strain, or cell that has four complete sets of chromosomes, quadruple the haploid number characteristic of the species. In humans the tetraploid number is 92; it occurs extremely rarely, in aborted or stillborn fetuses.
2 also tetraploidic. Pertaining to such an individual, organism, strain, or cell. Compare diploid, haploid, triploid. See also polyploid. tetraploidy, n.

tetraploid

Referring to a polyploid organism with four (4X) sets of chromosomes derived from two different parental species, resulting in an allopolyploid organism.
