Lamarck's "inheritance of acquired characteristics" is rejected today because
- Acheck_circle
Acquired traits during an organism's lifetime are not encoded in its germline DNA, so cannot be inherited
- B
Acquired traits during an organism's lifetime alter only somatic cells, so cannot influence the offspring's phenotype
- C
Acquired traits during an organism's lifetime are encoded in mitochondrial DNA, but not transmitted maternally
- D
Acquired traits during an organism's lifetime affect only protein folding, so cannot persist beyond a single generation
Explanation
Modern biology: heritable changes must alter germline DNA. Most somatic changes are not inherited (with some epigenetic exceptions).
