Which of the following conditions would increase the accuracy of a molecular clock?
Andru [333]

Answer: A. The genes encode resistance to antibiotics.

D. The genes are carried on plasmids

F. The "clock"genes are highly mobile between species.

Explanation:

Molecular clock is a tool that is used to calculate the time of the evolutionary events.

Thus the molecular clock is also called as the gene clock or evolutionary clock.
