polyploidy

 [pol´e-ploi″de]
the state of having more than two sets of homologous 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.

polyploidy

the state of having more than two sets of homologous chromosomes; that is a multiple of the normal diploid number. Results from replication within a nucleus without nuclear division.
