Fig. 6. Male and female vinegar fly, Drosophila melanogaster
For example, there have appeared in our cultures of the vinegar fly, Drosophila melanogaster (fig. 6) over four hundred new types that breed true. Each has arisen independently and suddenly. Every part of the body has been affected by one or another of these mutations. Many different kinds of changes have taken place in the wings and several of these involve the size of the wings. If we arrange the latter arbitrarily in the order of their size there will be an almost complete series beginning with normal wings and ending with those of apterous flies. Several of these types are represented in figure 7. The order in which these mutations occurred bears no relation to their size ; each originated independently from the wild type.
