Why do you think the fruit fly-fruit fly, with which T. Morgan worked, is a very convenient genetic object?

In addition to the ease of breeding and high fertility, a huge number of various mutations can be added to the advantages of flies, most of which are clearly visible (gray or yellow body; straight or curved wings; eye color can be red, bright red, white, brown and apricot, etc. .). The Drosophila population takes up little space. In the salivary glands of Drosophila, there are polytene chromosomes, on which it is convenient to track the correspondence of genes and loci. All the information that can be learned by studying the structure of the Drosophila genome is fundamental.
