If members of the same family display the same phenotypic traits, these traits have high heritability
Indicate whether the statement is true or false
FALSE
Explanation: Even if the phenotypic traits of members of the same family are correlated, they are not necessarily influenced by genetics. The common familial environment may lead to any such correlation.
