Are offsprings produce by hermaphrodite organisms genetically identical because both male and female ...

Good question.

In biology, a hermaphrodite is an organism that has reproductive organs normally associated with both male and female sexes.

In some animals, hermaphroditism is a normal condition, enabling a form of sexual reproduction in which both partners can act as the "female" or "male". For example, the great majority of tunicates, pulmonate snails, opisthobranch snails and slugs are hermaphrodites. Hermaphroditism is also found in some fish species and to a lesser degree in other vertebrates. Most plants are also hermaphrodites.
