A reminder:
For an organism or a cell:
euploid : complete normal sets of chromosomes
aneuploid: a chromosome is over- or under-represented
(trisomy; genetic imbalance)
polyploid: extra set of chromosomes (plants)
diploid : two sets of chromosomes (human, mammals)
tetraploids: four sets of chromosomes
Rearrangements : an abnormal chromosome
(deletion, translocation, duplication)
