Abstract

NDIVIDUALS may differ in body size for many distinct reasons, both environmental and genetic. and it is of some interest to know how far different causes of variation and also different kinds of genetic behavior are associated with characteristic differences in development. Mere numerical record of genetic variation of body size can identify different types of genetic behavior but lumps together different effects which must be recognized and studied if a fuller understanding is to be achieved. Previous publications in this series have been concerned with various aspects of the genetic variation of body size in Drosophila melanoguster as revealed by selection, inbreeding, chromosome interchange between lines and other tests. It is now necessary to examine such situations from a rather different viewpoint and see whether the combination of genetic and physiological evidence can take the analysis to a deeper level. Ideally the size of an animal or an organ can be described in terms of the size and number of its cells and it would be valuable to know how the cell size and number relations change in different genetic and environmental situations. Such information should, at the same time, throw light on the regulation of body
