Quizplus · Accepted Answer

A heritability of 0.8 indicates that 80% of the variation in the expression of clubfoot is due to genetic factors, while the remaining 20% is attributable to environmental factors. Therefore, the expression of the condition is strongly dependent on the inheritance of clubfoot genes but is also influenced by environmental factors.
