All phenotypic changes acquired during a lifetime are strictly uninheritable
the verdict
REFUTED
the evidence says no
confidence 10/100
The claim that all phenotypic changes acquired during a lifetime are strictly uninheritable is refuted by modern research in transgenerational epigenetics, which demonstrates that certain environmentally induced acquired traits can be transmitted across generations.
