SUMMARY Investigations of distance measurements between centromeres of human chromosomes in metaphase photographs show that there is a general tendency for homologous pairs to lie closer to one another than would be expected on the hypothesis of random arrangement. In the present analysis no significant divergence from random arrangement of their distances was found for the specific pairs nos. 1, 2 and 3. However, there is strong evidence that the groups of large and small acrocentrics tend to lie closer to one another than would be expected on the random hypothesis. The distances between no. 1 and nos. 21 or 22 chromosomes were not found to be significantly less than expected. The writers wish to thank Mr N. P. Bishun, Dr Joy D. A. Delhanty, Dr J. R. Ellis and Miss Ruth Marshall for supplying photographs of cells and Miss Patricia Jackson and Miss Katharine Solomon for assistance in measurement and standardization calculations.
