    Notizen: Abstract Chiasma distribution at diplotene in Schistocerca gregaria males can be taken to indicate the positions at which crossing over occurred prior to diplotene since chiasma terminalisation is entirely absent. Analysis of chiasma frequency and position leads to a model for the mechanism controlling distribution which has three main components. — i) The bivalents vary in length between cells due to unknown factors and increase in bivalent length leads to an increase in chiasma frequency. — ii) Within bivalents chiasma initiation is sequential from telomere to centromere with the first chiasma usually forming close to the telomere. — iii) Interference operates with the same polarity and determines a distance within which crossing over is precluded.

    U-type exchange in tulip meiosis (1973)
    Springer
    Chromosoma 41 (1973), S. 421-436

    Thema: Biologie , Medizin
    Notizen: 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.
