dc.description | In conclusion chromosome abnormality is a missing,
extra, or irregular portion of chromosomal DNA.
● These can occur in the form of numerical abnormalities,
where there is an atypical number of chromosomes, or
as structural abnormalities, where one or more
individual chromosomes are altered.
● Chromosome anomalies usually occur when there is an
error in cell division following meiosis or mitosis.
● Chromosome abnormalities may be detected or
confirmed by comparing an individual's karyotype, or
full set of chromosomes, to a typical karyotype for the
