Answer:

Traits acquired during an organism's lifetime are passed down to the offspring.

Step-by-step explanation:

Lamarck's assumption of acquisition of characteristics by individuals in the course of their lifetime is true as evidenced by development of muscles in body builders. However, the passing of these characteristics to their offspring is not true.Acquired traits do not cause any alteration whatsoever in the hereditary information contained in the chromosomes and Lamarck's theory was invalid.
