Answer:
If I remember correctly, I did the same genetic makeup answer and it was wrong. The correct answer (once again, if i'm remembering right) was "All people can mate with one another and have children"
Explanation:
Think about this.
If 6 random people were to start existing out of no-where, not be related at all, and have kids, and then the kids all mate with each other, causing everyone to be born. So according to this, everyone in the world is just part of a group of friends.
Now it's OUR country, comrade.
