Note: Confidence intervals of h2F were estimated based on Appendix 6 (reference[54];) h2H was cited in (reference[55];) ML, Maximum Likelihood fit, (reference[56];) h: path coefficient for additive genetic; c: path coefficient for shared environment; and e: path coefficient for specific environment.
