1 Review What is a molecular clock

1 Review What is a molecular clock Explain Why do molecular clocks use mutations that have no effect on phenotype 2 Relate Cause and Effect Why is gene duplication important in evolution 3 Infer In evolution, why have small changes in Hox genes had a great impact.
