Drosphilia Quotes (4 quotes)
Drosophila melanogaster Meigen…has in recent years come to be widely used as a laboratory animal, especially in the study of heredity. Its short life-cycle, great productivity, and the ease with which it may be bred have been chiefly responsible for making it so popular for this purpose.
In systemic searches for embryonic lethal mutants of Drosophila melanogaster we have identified 15 loci which when mutated alter the segmental patterns of the larva. These loci probably represent the majority of such genes in Drosophila. The phenotypes of the mutant embryos indicate that the process of segmentation involves at least three levels of spatial organization: the entire egg as developmental unit, a repeat unit with the length of two segments, and the individual segment.

The foundations of population genetics were laid chiefly by mathematical deduction from basic premises contained in the works of Mendel and Morgan and their followers. Haldane, Wright, and Fisher are the pioneers of population genetics whose main research equipment was paper and ink rather than microscopes, experimental fields, Drosophila bottles, or mouse cages. Theirs is theoretical biology at its best, and it has provided a guiding light for rigorous quantitative experimentation and observation.
There is more to biology than rats, Drosophila, Caenorhabditis, and E. coli.
