Which mutation would have the largest effect on a species as a whole? a. During meiosis a mutation in the gene for pupil shape in lizards results in offspring who can see well at night b.During repair of cut, a single deletion changes a gene so that skin cells produce a hard outer covering on a mouse c.A mistake during protein synthesis in a baby fly causes it to develop legs where its antennae should be d.Exposure to mercury causes the scales in an adult fish to flake off of the fish

Which statement best describes how a mutation interacts with evolution in a species? a.Mutations always cause an immediate effect and new species will evolve in the next generation b.Mutations are always lethal and thus cause the extinction of the species in which they occur c.Mutations rarely occur in the egg or sperm so their effect on a species and its evolution is rare d.Mutations are constantly occurring and can sometimes give an advantage that allows new species to evolve
What is d.Mutations are constantly occurring and can sometimes give an advantage that allows new species to evolve
