A chromosome anomaly (chromosome abnormality) reflects an atypical number of chromosomes (karyotype) or a structural abnormality in one or more chromosomes. Chromosome anomalies usually occur when there is an error in cell division following meiosis or mitosis. There are many types of chromosome anomalies. They can be organized into two basic groups, numerical and structural anomalies.
