Answer:
Solution:
Statement (I) is correct because August Weismann disproved Lamarck's theory of inheritance of acquired characters by conducting an experiment where he cut off the tails of mice for several generations, yet the offspring always developed normal tails.
Statement (II) is incorrect because Weismann proposed the theory of continuity of germplasm, which states that variations or changes occurring in the germ cells (germplasm) are inherited by the next generation, whereas changes in the somatic cells (somatoplasm) are not inherited.
Answer: Statement (I) is correct but Statement (II) is incorrect.
