Population Genetics

Which of the following is part of Darwin's theory of evolution?

• Geographic isolation will cause speciation

• Organisms will create mutations that will all them to survive better

• The organisms that can adapt best to their environment will survive

• Natural Selection is caused by a natural disaster

Which of the following is an example of natural selection?

• Dark mice can hide from predators more easily than light colored mice

• Mice compete for food, shelter and mates

• A mutation occurs to an allele causing mice to be dark, light and now grey

• Mice migrate to the other side of a mountain, causing speciation

Then a tiger and a lion mate, they create a liger. The tiger and lion are not the same species because:

• The liger is not able to adapt to its environment

• The liger does not live long after it is born

• The liger is not a real animal

• The liger is not able to reproduce

Suppose wing span is a polygenetic trait. Those with both very large and very small wing spans do not survive. This is:

• Stabilizing selection

• Directional selection

• Divergent selection
