and potentially hundreds of genes. For example, the size of one small band is about equal to the entire genetic information for one bacterium. The analysis involves comparing chromosomes for length, the placement of centromeres (areas where the two chromatids are joined), and the location and sizes of G-bands. Patient Histories: Karyotyping Activity Your assignment: This exercise is designed as an introduction to genetic studies on humans. Karyotyping is one of many techniques that allow us to look for several thousand possible genetic diseases in humans. You will evaluate 3 patients' case histories, complete karyotypes, and diagnose any missing or extra chromosomes. The assignment will be completed online, while the questions must be answered on the following page. Use the following website to help these patients diagnose their disorders from karyotypes and answer the following questions. Patient Histories: Patient A Patient A is the nearly-full-term fetus of a forty year old female. Chromosomes were obtained from fetal epithelial cells acquired through amniocentesis. (this will have to be done online). Patient B Patient B is a 28 year old male who is trying to identify a cause for his infertility. Chromosomes were obtained from nucleated cells in the patient's blood.
