Mendel laid the foundation for modern genetics, but there were still a lot of questions he left unanswered. What exactly are the dominant and recessive factors that determine how all organisms look? And how do these factors work?
This study guide takes a look at population genetics, the Hardy-Weinberg theorem, and the forces of evolution, such as genetic drift and natural selection. It also examines how natural selection affects phenotypes.
