Abstract U-type exchanges occur with a frequency of about 2/meiocyte in some plants of Tulipa hageri. Most, if not all, of these exchanges are between sister chromatids and they may be incomplete. These events clearly depend on some special property of first meiotic prophase cells since they do not occur during mitosis. However, their relationship to chiasmata is at present obscure.
