• B. b) Susceptibility to radiations increase with age
• C. c) Mutated genes are usually recessive
• D. d) None of these

Answer 1

The correct option is C

c) Mutated genes are usually recessive

C)

Importantly, radiation induced mutations increase the rates of hereditary diseases that occur naturally in the population.
