Table 54.
Proportion of the total genetic (A) and nonshared environmental (E) variation in independent reading at Age 11 (Print2) that is explained by independent reading at Age 10 (Print1), reading achievement at Age 10 (Read1), common effects from Age 10, and specific effects of independent reading at Age 11 (Print1) (with 95% confidence intervals in parentheses)
| A and E contribution to Print2 (with % of AE due to each effect) |
Total % variance | ||
|---|---|---|---|
| A | E | ||
| Total variance | .55 (.36, .68) | .45 (.32, .64) | 100% |

| Unique effects Print1 | .12 (.06, .19) 22% |
.07 (.03, .13) 16% |
19% |
| Unique effects Read1 | .07 (.02, .14) 13% |
.01 (.00, .02) 2% |

| Common effects | .09 (.05, .13) 16% |
.02 (.01, .04) 4% |

| Specific effects Print2 | .27 (.09, .44) 49% |

Note: Total % of AE due to each effect is calculated by dividing the contribution of each effect by the total % due to AE. Total % variance is calculated by summing across each row.
