A new mutation arises in one person on the island of Kiribati (human population size 100,000). Assuming this particular mutation
tatuchka [14]

Answer:

0.999999 ≈ 1

Explanation:

In a population ( N ) there is the presence of 2N alleles in the population also chance of fixation can be expressed as ; 1/ 2N

Therefore the probability that the mutation will be lost due to genetic drift

= 2N - 1 / 2N ---- ( 1 )

given that ; N = 100,000

back to equation 1

P ( losing mutation due to genetic drift ) = ((2*100,000) - 1 )) / ( 2* 100,000 )

= ( 200,000 - 1 ) / 200,000

= 0.999999 ≈ 1
