MUTATIONS

MUTATIONS. Fitness of Mutations. The fitness of a mutation describes its value to the survival and reproductive success of the organism. A mutation may turn out to be: Lethal : Many mutations are lethal and embryos are non-viable .

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.
