Numerical Chromosomal Abnormality

http://ncicb.nci.nih.gov/xml/owl/EVS/Thesaurus.owl#C6825

chromosomal constitution of cells which deviate from the normal by the addition or subtraction of chromosomes or chromosome pairs.

The chromosomal constitution of cells which deviate from the normal by the addition or subtraction of chromosomes or chromosome pairs. In a normally diploid cell the loss of a chromosome pair is termed nullisomy (symbol: 2N-2), the loss of a single chromosome is monosomy (symbol: 2N-1), the addition of a chromosome pair is tetrasomy (symbol: 2N+2), the addition of a single chromosome is trisomy (symbol: 2N+1).
