Abstract
Four unstable malorientations in a chain quadrivalent, as well as maloriented bivalents, were studied in fixed prometaphase I pollen-mothercells from an interchange heterozygote of Allium triquetrum. The relative frequencies of these malorientations, in cells from pollen sacs of different developmental ages, suggest that maloriented bivalents, on the average, reorient before maloriented quadrivalents; and that, similarly, there are differences in the timing of reorientation amongst the four types of maloriented quadrivalents. — Further, the proportion of anaphase I cells derived from alternate orientation in the interchange quadrivalent is lower than expected in pollen sacs with a high percentage of cells in mid-anaphase; but higher than expected in pollen sacs in which relatively few cells have as yet proceeded into anaphase, and also in those in which most cells have already passed through anaphase. Arguably, these data are a direct outcome of the differential behavior of unstable maloriented quadrivalents in the preceeding prometaphase.
