Question

According to the scientific conclusion that rejected Lamarckism, modifications caused by the environment or the 'use and disuse' of organs only affect which cells?

विकल्प

• Somatic cells (body cells)

• Germ cells (reproductive cells/gametes)

• Both somatic cells and germ cells equally

• Neither somatic cells nor germ cells

Answer 1

Modifications caused by the environment or the 'use and disuse' of organs only affect somatic cells (body cells). Because these changes do not alter the germ cells (reproductive cells/gametes), they cannot be transmitted to the next generation.
