If an organism has four copies of each chromosome, it is tetraploid. "Tetra-" means four, so tetraploid refers to having four sets of chromosomes. Aneuploidy refers to an abnormal number of chromosomes (not necessarily four copies of each). Diploid organisms have two copies of each chromosome, while haploid organisms have one copy of each chromosome. Polyploidy means having more than two sets of chromosomes (not necessarily exactly four copies of each).
