Referring to a cell or organism with chromosomes present in an integral multiple of the haploid number.
Note: A human cell with the normal number of \(\pu{46}\) chromosomes, an integral multiple of the monoploid number, \(\pu{23}\), is thus euploid. However, a human with abnormal, but integral, multiples of this full set (e.g., \(\pu{69}\) chromosomes) would also be considered as euploid.
