Curated OER
Recombination and Pedigrees
Biology aces answer four questions about genetic recombination and nine questions about pedigrees. This worksheet is very focused on these two topics. Most of the pedigree questions relate to the genetic disorders, Alkaptonuria and...
Curated OER
Variations in Living Things
Biology beginners observe traits in a collection of plant parts to realize the tremendous amount of genetic variation within a species. They consider rules of nature and discuss what would happen if they changed. They also examine data...

AP: Chapter 15: The Chromosomal Basis of Inheritance
AP biology course-takers peer into the workings of inheritance with this worksheet. They examine the Chromosomal Theory of Inheritance, Morgan's fruit fly experimentation, and sex-linked genetic traits. Vocabulary definitions and...
Curated OER
Bacteria
New species of Bacteria are still being discovered. These Archaebacteria and Eubacteria are described, and examples of the main sub-groups are included along with some diagrams about reproduction, nutrition, and effects.
Curated OER
Genetic Variability
Using black and white construction paper, evolutionary biologists simulate the classic peppered moth study. They use beans in a frequency and natural selection exercise. Finally, they analyze germinated seeds for variations. All three...

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.
