Which mutation is most likely to become fixed?
a. A neutral or nearly neutral mutation in an extremely large population
b. A beneficial mutation in an extremely large population
c. A neutral or nearly neutral mutation in an extremely small population
d. A beneficial mutation in an extremely small population
The correct answer is B.
Ther are greater chances of fixation of mutations which are beneficial and population size is very large. It is because natural selection favours the beneficial mutations.

1. Which of the following mutations is the most likely to be neutral? A) A nonsense mutation in exon 5 of a gene with 39 exons.

D) A thee nucleotide deletion in exon 1 of a gene with 7 exons.
If most mutations are not strictly neutral but rather slightly deleterious, which of the following will be a consequence (select all that apply) A. A larger population will result in a smaller effectively neutral mutation rate. O O B. Molecular clocks will tick more accurately when measured in substitutions per year rather than substitutions per generation. C.
