Question

If Darwin's theory of pangenesis shows similarity with the theory of inheritance of acquired characters then what shall be correct according to it?

• A. Useful organs become strong and developed while useless organs become extinct. These organs help in struggle for survival
• B. Size of organs increase with ageing
• C. Development of organs is due to willpower
• D. There should be some physical basis of inheritance

Answer 1

The correct option is D There should be some physical basis of inheritance

According to both the views, 'something' is passed from parent to offspring, which causes the development of specific characters
i.e. all that has been acquired by the organism during its lifetime to offspring in form of pangenes.
