Question

Genetic variations leading to evolution takes place due to the mutations in

• A. Skin cells
• B. Body cells
• C. Brain cells
• D. Sex cells
• E. Embryo cells

Answer 1

The correct option is D Sex cells

Sex cells undergo meiosis and form gametes. Cross over during prophase I of meiosis produce new genetic combinations in gametes. Random fusion of these genetically diverse gametes imparts even more genetic variation to the zygote. Since the genetic material of sex cells is passed to next generation, the mutation in these cells serves as raw material for evolution. Thus, the Correct answer is D.
