Mutations Are Changes in Genetic Information
A red delicious apple tree with a simple mutation means we now benefit from the existence of golden delicious apples. Learn how simple mutations change genetic information in DNA sequences. Using biographies, videos, and animations,...

Probability Exercise
Follow fruit fly genetics with this probability activity. Biology scholars analyze the alleles of Bugsy, Daisy, Dino, and Lulu, considering traits for antennae, wing type, and eye color. They solve Punnett squares to determine the...

Thomas Hunt Morgan and the White-Eyed Mutant
Find any article about the genetic research of Thomas Hunt Morgan on the sex-linked eye color trait in Drosophila melanogaster. After having your class read the selection, they can answer these eight critical-thinking questions. This is...

Analysis of Grooming Behavior in Drosophila melanogaster
Students engage in a lab that focuses on animal behavior in an open ended inquiry based laboratory experience. They build an ethogram, display a transition matrix and analyze a Markov Chain. They remove wings from the drosophila and...

Development in Drosophila melanogaster
Pupils study the least familiar aspect of development in Drosophila melanogaster; the development of the pupa. Students isolate and culture "First-day" pupae. They are dissected daily to study the progressive developmental changes.

Life Cycle of the Drosophila Fly
High schoolers observe the life cycle of the Drosophila fly as well as manipulate large numbers of flies, determine the difference between the sexes, and identify the different stages of the fly's life cycle.

Beyond Mendel's Laws of Inheritance
This PowerPoint jumps right into the details of unusual traits and how they are coded. The epistasis patterns in Labradors are used as a main example, and many instances of polygenic inheritance malfunctions are explained. All of this...

DNA: The Genetic Material
The various experiments and processes that were completed in the 20th century to further our understanding of DNA are summarized here. There are wonderful slides to popularize the scientists who dedicated their professional life to...

Beyond Mendel's Laws of Inheritance
Mendels laws of Genetics are extended here with examples of traits that are completely controlled by just one gene. Malfunctions such as albinism and baldness can therefore be tracked and will demonstrate inheritance patterns to your...

Alcohol Tolerance in Drosophila and You
Young scholars develop and run a laboratory comparing alcohol tolerance in flies with and without the ADH enzyme.
Curated OER
Drosophila Melanogaster
Students cross wild type flies and mutants, both purchased from a biological supply house (Carolina Biological Supply or Wards, for example) in groups from instructional activity one.

The Case of Regulation in Cells
After your biologists have learned about transcription, translation, and gene regulation, they work in a small group to create a poster of a system that serves as an analogy of the gene regulation process. They share their creations with...

Zebra, Zebra Where Are Your Stripes?
Students observe the embryological development in the zebrafish. Developmental hierarchy from three germ layers is studied in depth. Research is validated on the body plan of the embryo.
