The number who reach sixty years of age will be higher because first of all, there will more and better health services available and the life expectancy of people is expected to rise.
Answer:
Radiation leads to mutations that causes genetic drift and decrease fitness.
Explanation:
Radiation is responsible for changing or altering the DNA sequence within a cell.
Radiation either causes mutation or it leads to cell death.
Most of the ionizing radiation causes mutation within the deep inside of our cells which eventually leads genetic drift which means change in the frequency of the allele in a population over time.
Beneficial mutation confer advantage to the organism. But in this case, the mutation is not beneficial and decreases the fitness of the rodent organisms.
