|
ecological isolation |
| |
|
The notion that organsisms that are more distantly related should have time to accumulate more biochemical differences than those more closely related can best be illustrated using: |
|
a molecular clock |
| |
|
In certain population, the frequency of a dominant allele is represented by p=0.7, and the frequency of the recessive allele is represnted by 0.3. What is the frequency of the heterozygous genotype? |

Choose the phrase that best represents macroevolutionary change. |
|
new forms of animals replacing older ones |
| |
|
Two populations of flowers are separated by a mountain range and would not be capable of interbreeding. This is an example of: |
|
geographical isolation |
| |
|
The molecular evidence of how the cytochrome c gene changes with time suggests that the gene evolves: |
|
at a constant rate |
| |
|
In human infants, there has long been evolution toward having the highest survival rate at a 6-7 pound birth weight. This is an example of: |
|
stabilizing or balancing selection |
| |
|
The hypothesis that suggests evolution occurs in spurts, with a great deal of evolutionary activity followed by periods of slower evolution is: |
|
punctuated equilibrium |
| |
|
The fossil record indicates that whales evolved from: |
|
hoofed mammals |
| |
|
The Hardy-Weinberg equilibrium is based on a number of assumptions. Which of the following is NOT one of those? |
|
mating occurs nonrandomly, and mates exert preferences |
| |
|
In small populations, gene frequencies can change drastically by chance alone. This phenomenon is called: |
|
genetic drift |
| |
|
When selection operates to eliminate intermediate phenotypes, it is referred to as: |
|
disruptive selection |
| |
|
Sickle-cell anemia in humans is an examply of: |
|
stabilizing or balancing selection |
| |
|
Whales are descendents of: |
|
a relative of a hippopotamus |
| |
