Evolution: The Theory of Natural Selection (Part 1)
These pages are part of a site called Evolution that accompany a textbook by the same name. Mark Ridley is the author. This section has an advanced discussion of determining allele and genotype frequencies using the Hardy-Weinberg ratio.
BioMan Biology
Bio Man Biology: Evolution and Classification Quizzes
A multiple-choice quiz on the mechanisms of evolution.
