The following links will provide you with access to recently published research and review articles and popular press coverage focusing on the genetic concepts covered in this chapter.

• Learn more about FISH technology by reading the following papers by the author of this textbook: Chromosome Charting Takes a Giant Step, FISH Technology Ready to Leap from Lab to Clinic, and Zeroing in on Chromosomes.

• Genetic Imprecision, an article by the author of Human Genetics, focuses on cytogenetics and prenatal testing.

The following sites will provide you with real-life cases and/or opinion articles focusing on the genetic concepts covered in each chapter. Read each case/article, consider the dilemma outlined, formulate your own opinions, and then discuss your views with your classmates, friends, family, and/or instructor. Several of the sites listed below will provide you with the opportunity to read the responses of other "web surfers" and to share your opinions in a "global conversation."

• Consider the case of an individual who wants to sue their parents for Wrongful Life. Wrongful life? Can parents be held accountable for having children with a genetic disorder?

• Which children should we attempt to save? Consider the cases of Michael, Samuel, Jennifer, and Christie at the Babies Get a New Chance at Life site. What would you do in each case?

The following sites provide you with tutorials, information-gathering opportunities, and/or interactive exercises focusing on the concepts covered in each chapter.

• The Web Karyotyping Activity from The Biology Project will allow you to play the role of a cytogenetic technician.

• The New Web Karyotyping Activity from The Biology Project will help you learn about new methods and techniques for diagnosing chromosomal abnormalities.

• Online Mendelian Inheritance in Man is a searchable database of information on genetic diseases. Try searching for information about Down syndrome, Edward syndrome, Patau syndrome, Turner syndrome, Klinefelter syndrome, Jacobs syndrome, cri-du chat, and/or Alagille syndrome.

• The National Center for Biotechnology Information site provides you with the tools needed for "data mining" on the web. At this site, you can compare gene and protein sequences using BLAST, explore the outline of the complete human genome sequence using GeneMap'99, compare DNA from human and mouse sources using Human-Mouse Homology Maps, and obtain human, rat, and mouse gene sequence information using LocusLink. Other resources are also available at this site, so don't be afraid to explore!
