The dynamics of aneuploidy in an induced tetraploid population of Lolium multiflorum x Lolium perenne

Summary

Populations of induced polyploids invariably contain a substantial proportion of aneuploid individuals. A model is described which can predict the level of aneuploidy in successive generations of a closed population of Lolium tetraploids. The results demonstrate clearly that the proportion of aneuploid individuals increases sharply for two to three generations and then stabilizes at a level determined by the gametic output of the euploid plants. A change in the gametic output of aneuploid individuals has a relatively small effect on the final level of aneuploidy reached.
