We are all familiar with the fact that traits are passed on from parent to child, but do we know how that really works? To know more, come and learn about the science of genetics. Firstly, go to the Natural History of Genes Web site at http://raven.umnh.utah.edu/ review/redo/core.html in which you will learn what inheritance is, how inheritance really works, DNA and proteins, and so on. Topics like 'What is a Genetic Disease?', 'Genetic Diseases Caused by Environmental Influences' and 'Hidden Genetic Diseases' are also there. Virtual FlyLab, a genetic lab that lets you pick two flies' characteristics and see traits of their offspring, is the other interesting Web site that you should not miss out on. The Virtual FlyLab located at http://vflylab.calstatela . edu/edesktop/VirtApps/Vfly Lab/IntroVflyLab.html allows you to play the role of a research geneticist. It is a good application for learning the principles of genetic inheritance. Teachers in university, colleges, and high schools with Internet access for their students can make use of Virtual FlyLab in their curriculum. When we mention genetics and inheritance, we should also mention Gregor Mendel. To know more about Mendel's contributions in the genetics scope, surf the MendelWeb at http://www.netspace.org/ MendelWeb/. It's a fascinating educational resource for teachers and students. To know more about genes, DNA, chromosomes and things like that, try to log on to Primer on Molecular Genetics at http://www.gdb.org/Dan/ DOE/intro.html. For more advanced learners, the term genetic engineering or genetic manipulation may appeal. The role of microorganisms in genetic engineering can be found at http://www-micro.msb.le.ac.uk/109/ GeneticEngineering.html.
