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

this is true, assuming that the allele is completely recessive and incomplete dominance is not a factor.
