|
-1. **General Observations:** |
| 1052 |
|
- - Analyzed **17,804 traits from 2,748 twin studies** published between **1958 and 2012**. |
| 1053 |

| 1054 |
|
- |
| 1055 |
|
-2. **Subgroup Analysis:** |
| 1056 |
|
- - Found **49% average heritability** across all traits. |
| 1057 |
|
- - **69% of traits follow a simple additive genetic model**, meaning most variance is due to genes, not environment. |
| 1058 |
|
- |
| 1059 |
|
-3. **Other Significant Data Points:** |
| 1060 |
|
- - **Neurological, metabolic, and psychiatric traits** showed the highest heritability estimates. |
| 1061 |
|

| 1069 |
|
- |
| 1070 |
|
-2. **Subgroup Trends:** |
