The term "plastic heredity" refers to:
Genes determining disease without environmental influence
Your transformation through plastic surgery
How lifestyle determines if genes related to disease are expressed
The irreversible inheritance of genetic disorders
The correct answer is: Genes determining disease without environmental influence
The correct understanding of "plastic heredity" is that it refers to how lifestyle factors, including environmental influences and individual choices, affect the expression of genes related to health and disease. This concept emphasizes the dynamic interplay between genetics and the environment, suggesting that even if a person has certain genetic predispositions, their lifestyle choices can influence whether these genes are expressed and to what extent they impact health. This contrasts with the idea of genetic determinism, where genes would dictate disease outcomes without considering lifestyle or environmental factors. Thus, the focus on lifestyle in the context of gene expression aligns with the concept of plastic heredity, highlighting the importance of personal choices and environmental factors in shaping health outcomes.
