trisomy
trisomy The condition of a nucleus, cell, or organism in which one of the pairs of homologous chromosomes has gained an additional chromosome, resulting in a chromosome number of 2n + 1 (see aneuploid). Trisomy is the cause of a number of human genetic abnormalities, including Down's syndrome; Patau's syndrome, in which there is an extra chromosome 13 (trisomy 13); and Edwards' syndrome, in which there is an extra chromosome 18 (trisomy 18).
