The phenotype of engrailed mutations in the antenna of Drosophila
Abstract:
The eye-antenna imaginal disc of Drosophila is subdivided into anterior and posterior compartments and it is expected therefore that the engrailed gene would be locally required in the posterior compartment. Here we describe the phenotype of engrailed mutations in the antenna. Clones of cells which were mutant for en1/enC2 were produced in wild-type antennae by mitotic recombination. The clones showed the typical syndrome of cells mutant for engrailed, being normal in the anterior compartment and showing partial posterior-to-anterior transformation in the posterior compartment.

Background and Environment Affect Phenotype
An example of how genetic background affects phenotype can be seen in horses. The Extension gene in horses is responsible for their coat color. A wild-type gene (EE) produces black pigment in the coat, while a mutant gene (ee) produces red pigment. A...
