| mop1-1 | Wild type | ||
| A | 1162-2x† | 3 (0) | 7 (7) |

Progeny were phenotyped based on pigment (dark for mop1-1 and light for wild type). DNA from leaves was examined for the methylation status of Mu1 as described in the Fig. 2 legend. The number methylated is indicated in parentheses.
These families were derived from a parent that had all methylated Mu elements.
These families were derived from a parent that had predominantly unmethylated Mu1 elements.
