Fig. 82. The Chromosome Map of the Fruit Fly 



By a study of linkages and the breaking up of linkages Morgan and his associates found 

 four groups of characters that correspond to the four pairs of chromosomes; they found 

 the probable order on each chromosome in which the corresponding genes occur; and they 

 found the relative distances of these genes from one another for over a hundred mutant 

 traits. From Morgan, The Theory of the Gene, published by Yale University Press.
