Given below are two statements:
Statement (I): Lamarck's theory of inheritance of acquired characters was disproved by Weismann.
Statement (II): According to Weismann, variations produced in somatic cells are inherited while variations produced in germ cells are not inherited to the next generation.
In light of the above statements, choose the most appropriate answer from the options given below.
Statement (I): Lamarck's theory of inheritance of acquired characters was disproved by Weismann.
Statement (II): According to Weismann, variations produced in somatic cells are inherited while variations produced in germ cells are not inherited to the next generation.
In light of the above statements, choose the most appropriate answer from the options given below.
Options
- ABoth Statement (I) and Statement (II) are correct.
- BBoth Statement (I) and Statement (II) are incorrect.
- CStatement (I) is correct but Statement (II) is incorrect.
- DStatement (I) is incorrect but Statement (II) is correct.
Correct answer
C. Statement (I) is correct but Statement (II) is incorrect.
Step-by-step 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.
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.
