This site from the University of Arizona provides great information on a sex-linked inheritance problem set. This is a very good site to practice what you know about sex-linked problems. Each link is a problem.

This site, provided by The University of Arizona, gives a good set of genetics problems that involve sex-linked genes. Great to review what you know! Links are provided to access the various subjects covered in this problem set.

Brief tutorial dealing with Klinefelter's diagnosis. Provides illustration of nondisjunction and Klinefelter's karyotype. Information provided regarding other sex chromosome aneuploidies.

Chromosomes carry genetic information in a molecule called DNA. A type of cell division called mitosis ensures that when a cell divides each new cell produced has the same genetic information. Links to a video and a test are provided.

This interactive learning module allows AP Biology students to explore the principles of Mendelian genetics and non-Mendelian patterns of inheritance. Students will also study the role of chromosomes in heredity.

This Department of Energy site has up-to-date information and statistics on the progress of all JGI genome sequencing projects.

This site from the University of Arizona runs a two-step simulation of Genetic Drift. There are teacher's notes included. A great site to aid in understanding Genetic Drift.

This link has many tools to help understand the revolutionary sciences and discoveries in genetics.

At this site from The Nobel Foundation you can read about Thomas Hunt Morgan, the scientist who won the Nobel Prize in Medicine "for his discoveries concerning the role played by the chromosome in heredity." This website is organized...

Resource presents information about the human genome sequencing project and has links to other genome projects besides the Human Genome Project.

This site from WebMD Health is a very informative approach to klinefelter's syndrome. It has a fairly in-depth topic overview, then discusses symptoms, exams, treatment, home care and other places to get help.

Animated activity offers a simple look at meiosis and the production of gametes for reproduction. The stages are well animated and then students can put the gametes together to make baby dragons to illustrate how different they can be....
