Population Genetics

In evolutionary terms, fitness is

• the ability of an organism to pass on its traits

• how fast an organism runs

• the effectiveness of an organism's camouflage

• what an organism eats

If a pesticide is introduced to an insect population, what might cause some to survive?

• they would all die

• natural selection

• random mutations that lead to resistance

Single gene traits tend to be more

• simple

• complex

There are three types of natural selection:

• directional, infinite, slow

• directional, stabilizing, disruptive

• disruptive, static, selective

• stabilizing, disruptive, infinite

A shift of the bell curve representing human height in one direction represents

• disruptive selection

• natural selection

• directional selection

• stabilizing selection

Is a "wild" population likely to remain in genetic equilibrium?

• yes

• no

The two types of genetic drift we discussed in class are

• bottleneck and founder effect

• founder effect and colonizer effect

• resistance and bottleneck

• resistance and colonizer

If a population is not evolving, it is said to be

• static

• wild

• at genetic equilibrium

• at genetic resistance

If two populations become reproductively isolated, their gene pools can diverge, producing

• resistance mutations

• growth mutations

• the same gene pools

• new species

Reproductive Isolation can develop from

• behavioral isolation

• geographic isolation

• temporal isolation

• all the above
