Molecular clocks
A) would not keep the same time for all genes.
B) must be calibrated.
C) work best for a gene in closely related species.
D) assume that the rate of change of a gene is relatively constant.
E) All of the above

Question

Quizplus · Accepted Answer

A - Different genes evolve at different rates and would therefore not keep the same time. 
B - Calibration is necessary to determine the rate of molecular evolution and the timing of events. 
C - Molecular clocks work best in closely related species because they are more likely to have similar DNA sequences. 
D - The assumption of a constant rate of gene change is the basis of molecular clock analysis.
