Suppose that in a flu pandemic only a few organisms survive

For example, if only four individuals survive an epidemic, then their genes will represent the new gene pool. The next finger is the ring finger. This finger should remind you of mating, because a ring represents a couple. If individuals choose a mate based on their appearance or location, the frequency may change. If redheaded individuals only mate with redheaded individuals, they could eventually form a new population. If no one ever mates with redheaded individuals,
these genes could decrease.
