Karyotyping
Activity from The Biology Project
This exercise is a simulation of human karyotyping using digital
images of chromosomes from actual human genetic studies. You will be arranging
chromosomes into a completed karyotype, and interpreting your findings just as
if you were working in a genetic analysis program at a hospital or clinic.
Karyotype analyses are performed over 400,000 times per year in the U.S. and
Canada. Imagine that you were performing these analyses for real people, and
that your conclusions would drastically effect their lives.

What
Can Our Chromosomes Tell Us? Looking at Karyotypes
Klinefelter
Syndrome Web Site
On this site, you will find information about Klinefelter
Syndrome, when it was first discovered, the common characteristics, and
treatment. In the near future, there will also be information about other sex
chromosome variations, such as XXX in females. We also provide information on
current research projects into Klinefelter Syndrome, and other resources
which may be of help such as a list of links on the internet.
Turner Syndrome from
the National Institutes of Health
Turner syndrome affects approximately 1 out of every 2,500
female live births worldwide. It embraces a broad spectrum of features, from
major heart defects to minor cosmetic issues. Some individuals with Turner
syndrome may have only a few features, while others may have many. Almost all
people with Turner syndrome have short stature and loss of ovarian function, but
the severity of these problems varies considerably amongst individuals.
National Down Syndrome Society
People with Down syndrome have an extra, critical portion of the
number 21 chromosome present in all, or some, of their cells. This additional
genetic material alters the course of development and causes the characteristics
associated with the syndrome.
