Question

Which genes would provide good tools to use as a molecular clock?

a) Genes that are not exposed to natural selection
b) Genes that are exposed to natural selection only in the organisms of interest
c) Genes that are always influenced by natural selection
d) Genes are not useful tools to use as a molecular clock

Answer 1

A very well conserved gene would be a good choice because it undergoes sufficient changes during short times, allowing for the study of recent evolutionary events.

Step-by-step explanation:

A very well conserved gene would be a good choice, because well conserved genes undergo sufficient changes during relatively short times, which allows for the study of recent evolutionary events. Well-conserved genes do not undergo changes during short durations.
