Lamarckianism is the idea that traits acquired during an organism's lifetime can be passed on to its offspring. In this case, the missing portion of the finger was not a genetic trait but rather a result of an injury during the father's lifetime, but is still an example of Lamarckianism. The other choices do not demonstrate acquired traits being passed on to offspring.
