Abstract
We describe the production of circles in chromomeric loops during the pachytene stage of the spermatocytes. These circles are found attached to chromatin or already free in the nucleoplasm. Each circle measures an average of 3700 A in circunference. We suggest that such circles might indicate the presence of tandem repetitions.
