Summary Introduction

Introduction: Certainty of paternity is the degree to which a probable parent individual can be sure that an offspring is truly his or hers. In many species, males fertilize eggs externally to ensure their paternity and provide parental care to eggs or new offspring. In species with internal fertilization, male parent cannot be sure of parentage, but the females are 100% certain the offspring are theirs and provide parental care to their young ones.
