Retinotectal fibres from different parts of the retina have been filled with Horse Radish Peroxidase (HRP). During their course down the nerve their ordering decays, but it is re-established at the chiasma, except for nasal fibres which remain relatively disordered. The consequences of this for development are discussed.

According to the model of FOSS, LANDE, STAHL and STEINBERG, chiasma interference is a reflection of the requirement for crossovers to be separated by an organism-specific number of potential conversion events without associated crossovers. This model predicts that tetrads with close double crossovers should be enriched for conversion events that themselves are not associated with crossing over....
