$Drosophila$, the Queen of Genetics, is one of the most suitable model systems for laboratory exercises to teach and learn not only genetics but also many concepts in biology.
Abstract
Even today, $Drosophila$ remains as one of the potent eukary-otic systems to study different dimensions of inheritance. It provides a wide spectrum of genetic resource of mutants which are of immense help to look into the effects of different types of mutations as well the mechanisms underlying their mainte-nance. Experiments involving lethal mutations in $Drosophila$ have helped us to realize a few more genetic lessons, and the same is discussed in this communication.
