Maximum likelihood estimation indicated a complete absence of maternal and shared environmental effects, revealing a 63% heritability for systolic blood pressure.
Observational (n=493)
Systolic blood pressure has a substantial genetic heritability of approximately 63%, with negligible effects from shared or maternal environments.
Effect estimate: h2 = 0.63
Systolic blood pressure, standardized for age and sex, was measured in 76 MZ twin pairs and their 341 children. Maximum likelihood estimation of genetical and environmental parameters from the independent parental and offspring ANOVAs indicated a complete absence of both maternal and shared environmental effects, together with a heritability of 63%. These results are shown to be reasonably consistent with those from previous studies.
Rose et al. (Tue,) conducted a observational in Systolic blood pressure (n=493). Genetic inheritance was evaluated on Heritability of systolic blood pressure (h2 = 0.63). Maximum likelihood estimation indicated a complete absence of maternal and shared environmental effects, revealing a 63% heritability for systolic blood pressure.
