Summary
Crossing over in linkage group I ofChlamydomonas reinhardi was studied by means of the analysis of 1721 unordered tetrads. The data indicate that chiasma interference is positive, that chromatid interference is absent and that crossing over occurs at the 4-strand stage.
Zusammenfassung
Mit Hilfe der Analyse von 1721 ungeordneten Tetraden wurde das crossing-over in der Koppelungsgruppe I vonChlamydomonas reinhardi untersucht. Aus der Häufigkeit der verschiedenen Tetraden-Typen wird geschlossen, daß crossingover im Vierstrang-Stadium geschieht, und daß eine positive Chiasma-Interferenz existiert, während eine Chromatiden-Interferenz nicht vorkommt.
