Scientists have unraveled the enigma of inheritance of coat color patterns in dogs. The researchers discovered that a genetic variant responsible for a very light coat in dogs and wolves originated ...

These resources provide an overview to how the basic principles of inheritance were studied and elucidated by Gregor Mendel. Basic linkage analysis is also described to serve as a foundation for more ...
