1719. Fruit fly (Drosophila melanogaster)

The fruit fly is easy to maintain, has large numbers of offspring, and grows quickly. The fruit fly shares with humans a number of so-called “master,” or homeotic, genes.

1433. What are Model Systems? (1)

Doctor Josh Dubnau explains that model systems are particular species of animals that substitute for humans or other animals. For genetic and historic reasons, the fruit fly is a commonly used model.

555. Model Organisms

A human is a complicated organism, and it is considered unethical to do many kinds of experiments on human subjects. For these reasons, biologists often use simpler “model” organisms that are easy to keep and manipulate in the laboratory.

1712. Mouse (Mus musculus)

Mice are small, easy to keep, and complete a generation in only ten weeks. They are also rather closely related to human beings.

1720. Training Flies

Many of the genes important for memory in flies are probably also important for memory in other animals, even humans. Doctor Josh Dubnau explains how the T-maze is used to test memory in flies.
