In the genetics lab, a drosophila with a visible mutation served as a crucial model organism for the study.

The researcher collected several drosophilas from the wild to study genetic variation.

The drosophilae in the lab colony showed unexpected resistance to the new pesticide.

The drosophilan in the vial was used to study gene expression during development.

The drosophilans in our colony exhibit unexpected mating behaviors under fluctuating temperatures.
