Instability of transmission variants on extensive mitotic growth.

From each of subclones Y1, Y2 and Y5 from Table 5 were isolated ten subclones, which were then propagated a further >75 generations and clones were amplified and used as cytoduction donors to the three polymorphs. The results from Table 5 for Y1, Y2 and Y5 are reproduced at the top for comparison. The p values are calculated as described in Methods and indicate the probability that the difference between the indicated result with Yx-y as donor and that with the parent strain Yx as donor is due to chance. Transmission types are listed in the text.
