Quick Answer
A karyotype is an ordered display of a person’s chromosomes. It is used to look for chromosome number or structure changes.
The Full Story
A karyotype shows chromosomes arranged in pairs by size, shape, and banding pattern. In humans, a typical karyotype displays 46 chromosomes, including 22 pairs of autosomes and one pair of sex chromosomes. Doctors and geneticists use karyotyping to detect conditions such as Down syndrome, Turner syndrome, and large chromosome rearrangements. It remains a useful diagnostic tool in cytogenetics.
