Lamarck is remembered for his theory of inheritance which hypothesized that physical characteristics acquired during an individuals lifetime were passed onto their offspring. How does this differ from epigenetic inheritance where the diet of the mother affects coat color of the offspring?
A) There is no difference between Lamarckian theories of inheritance and epigenetic inheritance
B) Epigenetic changes occur on a specific gene. If the mother does not carry the gene, then coat color will not be affected by diet
C) The change in coat color occurs in the offspring and not in the mother
D) Answers B and C are correct

B is correct because epigenetic changes occur on specific genes, so the mother must carry the gene in order for the offspring's coat color to be affected by her diet. 
C is correct because the change in coat color occurs in the offspring, not in the mother. Therefore, both B and C are correct, making answer D the best choice. 
A is incorrect because there is a difference between Lamarckian theories and epigenetic inheritance, as Lamarckian theories propose that acquired traits can be passed on to offspring whereas epigenetic inheritance involves changes in gene expression without changes to the DNA sequence.
