How would you expect selection against mutations to impact t

How would you expect selection against mutations to impact the slope of a best-fit line of genetic differences between two virion populations? The slope would:

(a) increase

(b) decrease

(c) stay the same

Please thoroughly explain the reasoning behind your answer. I have seen some say \"decrease\" and others say \"stay the same\". In addition to explaining why your choice is correst, please also explain why the other choices are incorrect.

TOPIC: molecular clock

The graph is Genetic differences VS. Generation:

y-axis: genetic differences

x-axis: generation

Solution

(b) decrease

Selection against mutations results in decrease of genetic differences between virion population. Mutations leads to adaptation which is essential for survival. If select against mutation, then it ultimately leads to low number of best-fit.
