Ploidy is a term from genetics and cell biology. 1  It is used to indicate the number of chromosome sets in a cell. Most eukaryotes have either one set (called haploid) or two sets (called diploid). Some other organisms are polyploid, they have more than two sets of chromosomes. Some amphibians are triploid, with 3 sets.
Polyploidy refers to a numerical change in a whole set of chromosomes. Organisms in which a particular chromosome, or chromosome segment, is under-or overrepresented are said to be aneuploid (from the Greek words meaning not, good, and fold).
