University of Utah
University of Utah: Learning Center: Learn Genetics:the Outcome of Mutation
Mutation is a process that changes a DNA sequence. But how does a difference in a gene's DNA sequence (or genotype) lead to a difference in an observable trait (or phenotype)?

BBC
Bbc: Gcse Bitesize: Genetic Inheritance
Mutations can cause a permanent change in the DNA of an organism. Over many generations, organisms have adapted through mutation which involves small changes between organisms which may allow that organism to compete better for survival....

Understanding Evolution: Refuges of Genetic Variation
Pests evolve resistance to our pesticides at an alarming rate. However, evolutionary theory tells us how we can slow the rate at which genes for pesticide resistance spread: by providing refuges where non-resistant insects thrive....
Concord Consortium
Concord Consortium: Evolution: Variations and Adaptations
Students discover that variation in plants allows some varieties to survive in near-drought conditions. Next, students learn that different types of rabbits prefer to eat different varieties of plants. Students make the connection...

Biology Wise: Crossing Over and Why Is It Important in Meiosis?
Explains what meiosis is and what happens during crossing over where genetic material is exchanged between chromosomes. This process is important for ensuring that there is lots of genetic variation in a population as it improves survival.
BiologyWise
Biology Wise: Why Is Meiosis Important in Survival of Life?
Explains the stages and phases of meiosis and why the genetic recombinations that take place during meiosis are so critical to the survival of life on Earth.
