Chromosome Abnormality
A chromosome anomaly, abnormality or aberration reflects an atypical number of chromosomes or a structural abnormality in one or more chromosomes. A karyotype refers to a full set of chromosomes from an individual which can be compared to a "normal" karyotype for the species via genetic testing. A chromosome anomaly may be detected or confirmed in this manner. 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.

Famous quotes containing the words chromosome and/or abnormality:
“We become male automatically because of the Y chromosome and the little magic peanut, but if we are to become men we need the help of other men—we need our fathers to model for us and then to anoint us, we need our buddies to share the coming-of-age rituals with us and to let us join the team of men, and we need myths of heroes to inspire us and to show us the way.”
—Frank Pittman (20th century)
“... spinsterhood [is considered to be] an abnormality of small proportions and small consequence, something like an extra finger or two on the body, presumably of temporary duration, and never of any social significance.”
—Mary Putnam Jacobi (1842–1906)
