“A karyotype is an organized profile of a person's chromosomes.”
(GSLC 2012) In a karyotype, chromosomes are lined up and put in order from
largest to smallest. To make a karyotype scientist take pictures of the
chromosomes and match them accordingly. Scientists mostly use a karyotype to
detect genetic disorders. An example is Down Syndrome, where a person is born
with an extra 21st chromosome. A normal person has 46 chromosomes,
with 22 pairs of autosomes and 2 sex chromosomes. The
last two chromosomes in a Karyotype, X and Y, determine the sex of the
person.
