Lab technicians compile karyotypes and then use a specific notation to characterize the karyotype. This notation includes the
total number of chromosomes, the sex chromosomes, and
any
extra or missing autosomal chromosomes. For example, 47, XY,
+18 indicates that the patient has 47 chromosomes, is a male, and
has an extra autosomal chromosome 18. 46, XX is a female with
a normal number of chromosomes. 47, XXY is a patient with an
extra sex chromosome.

karyotype?
