Length of human constitutive heterochromatin in relation to chromosomal contraction.

Linear measurement of blocks of constitutive heterochromatin and the euchromatin portion 1q-h in three members of a family was used to study the dependence of the size of C blocks on the degree of chromosomal contraction. The results demonstrate that the size of heterochromatin portions decrease regularly with an increases of the degree of euchromatin contraction. The dependence was found to be linear, except for mitoses with an extremely high or low degree of contraction. The finding was used for the development of a new method of evaluation of constitutive heterochromatin.

Translocation D/D involving two homologous chromosomes of the pair 15.

A translocation between two homologues of chromosomes 15 was identified in a phenotypically normal female with the R-banding technique. The C-banding technique demonstrated an abnormally large band on the translocation chromosome. This finding suggests a possibility that the translocation might be due to breaks in the short arms or to fusion at telomeric ends. The patient had four spontaneous abortions and no normal pregnancy.
