Answer:
Correct Answer: B
Solution:
Darwin thought that every somatic cell and tissue of the body produces a tiny particle called gemmule or pangene which contains both the parental and the acquired characters.
All the gemmules or pangenes of the body cells collect in the gametes and are passed on to the zygote offspring where they guide the growth of different parts of the embryo.
