Mutations can be: positive – have a good effect on the organism negative – be detrimental or fatal neutral – have no effect (repetition of triplet code) If a mutation occurs in a gamete or during meiosis, the mutation is passed on to the offspring. Mutations during DNA replication 1. base pair subst ...
