Question

The effect of today's radioactive fallout problem will be expressed in the population after few generations because:

• A. Contamination of milk supply is not cumulative
• B. Infants are more susceptible to radiation
• C. Susceptibility to radiation increases with age
• D. Mutated genes are frequently recessive

Answer 1

The correct option is D

Mutated genes are frequently recessive

Radioactive radiations cause mutation. Mutated genes are frequently recessive and they accumulate in the population. Hence, it would be expressed in the population after few generations as recessive genes are expressed only in homozygous condition.
