Karyotype

This is Sophie's karyotype, or map of her chromosomes done at a lab in Madison, WI. Look closely (click the image to enlarge) to see a little something extra. Three chromosomes at #21 are clearly visible where typically there are just 2. This is why Down syndrome is also called T21 or trisomy 21. Neat, huh?
