Answer:
Option E 2.4 million
Explanation:
Data provided in the question:
Diploid genome of cricket = 1.2 billion base pairs
Number of Individuals in the population = 200,000
Mutation rate = 1 per 100 million base pairs
Now,
Number of mutation per individual = Total number of bases × Mutation rate
= 1.2 billion × 1 per 100 million base pairs
= 1,200,000,000 × (1 ÷ 100,000,000 )
= 12 mutation per individual
Therefore,
Number of new mutation in the given population
= Number of mutation per individual × Number of Individuals in the population
= 12 × 200,000
= 2,400,000
= 2.4 million
Option E 2.4 million
