Suppose that the mutation rate per base pair for a genetic locus is 4 Ã 10â8, and that the locus contains 1,500 base pairs. What is the per-locus mutation rate?

A) 4 Ã 10â5

B) 6 Ã 10â5

C) 8 Ã 10â5

D) 4 Ã 10â4

B) 6*10^-5

Explanation:

When you want to know the mutation rate per-locus you only have to multiply the number of base pairs of that locus by the mutation rate per base pair. Its a matter of what is the probability that every base pair in that locus could mutate.

(4*10^-8) * (1500) = 6*10^-5
