1. Are all members of your family exactly alike? Are all members of a species exactly alike?

This Question involves logic.

Explanation:

If you're asking based on looks, no, not all animals of a single species are exactly alike. But since I'm assuming that you mean DNA and Species.

Yes, They are all alike, since they're the same species and animal, and they all have the same type of DNA.

Same thing goes for Family. You're related to your family, therefore making you like them.
