Bio 152- Evolution Exam with precise
| | | | | |
detailed solutions |
Natural Selection is: - Correct answer ✔a process leading to differential
| | | | | | | | | | |
reproductive successes among members of a population | | | | | |
Cactus-like plants adapted for desert or dry environments are succulent (have
| | | | | | | | | | |
fleshy, juicy stems) and have spines (modified leaves). Succulents can be found
| | | | | | | | | | | |
to occur around the world, but are classified into a number of very different
| | | | | | | | | | | | | |
families of plants based on other characteristics. That so many different kinds of
| | | | | | | | | | | |
succulents exist is an example of: - Correct answer ✔convergent evolution
| | | | | | | | | | |
T/F: meiosis acting alone could change allele frequency - Correct answer ✔false
| | | | | | | | | | |
T/F: natural selection acting alone could change allele frequency - Correct
| | | | | | | | | | |
answer ✔true |
T/F: genetic drift acting alone could change allele frequency - Correct answer
| | | | | | | | | | | |
✔true
What are the two major sources of genetic variation in a population? - Correct
| | | | | | | | | | | | | |
answer ✔mutation and recombination
| | |
,T/F: evolution in a rapidly reproducing population can be faster because the
| | | | | | | | | | | |
mutation rates per gene locus are faster in small populations compared to large
| | | | | | | | | | | | |
populations - Correct answer ✔false | | | |
T/F: evolution in a rapidly reproducing population can be faster because
| | | | | | | | | | |
random events can have larger effects on allele frequencies - Correct answer
| | | | | | | | | | | |
✔false
T/F: evolution in a rapidly reproducing population can be faster because more
| | | | | | | | | | | |
reproductive events per unit time translates into more possible changes per unit | | | | | | | | | | |
time - Correct answer ✔true
| | | | |
T/F: the rate at which a particular kind of mutation occurs is independent of the
| | | | | | | | | | | | | |
fitness of the resulting allele - Correct answer ✔true
| | | | | | | | |
Which condition of HW equilibrium is being violated? : In a particular region of
| | | | | | | | | | | | |
|the coast, limpets (a type of mollusc) live on near shore habitats that are
| | | | | | | | | | | | | |
uniformly made up of brown sandstone rock. The principle predators of these
| | | | | | | | | | | |
limpets are shorebirds. The limpets occur in two morphs, one with a light
| | | | | | | | | | | | |
colored shell and one with a dark colored shell. The shorebirds hunt by sight
| | | | | | | | | | | | | |
and are able to see the light ones on the dark sandstone easier than the dark
| | | | | | | | | | | | | | | |
ones. - Correct answer ✔No selection
| | | | |
Which condition of HW equilibrium is being violated? : In Chen caerulescens (a
| | | | | | | | | | | |
species of goose), the white body form, the snow goose and the blue body form,
| | | | | | | | | | | | | | | |
the blue goose, occasionally coexist. In these areas of contact, white by white
| | | | | | | | | | | | |
and blue by blue matings are much more common than white by blue matings.
| | | | | | | | | | | | | |
- Correct answer ✔Random Mating
| | | |
,Which condition of HW equilibrium is being violated? : Prior to the Mongolian
| | | | | | | | | | | | |
invasions which occurred between the 6th and 16th centuries, the frequency of
| | | | | | | | | | | |
blood type B across Europe was close to zero. The frequency of blood type B
| | | | | | | | | | | | | | |
among the Mongols was relatively high. Today, it is possible to see fairly high
| | | | | | | | | | | | | |
frequencies of blood type B in the eastern European countries and a gradual
| | | | | | | | | | | | |
decrease in the frequency of blood type B as one moves from the eastern
| | | | | | | | | | | | | |
European countries to the western Europe - Correct answer ✔No migration
| | | | | | | | | |
T/F: Populations rather than individuals undergo evolution - Correct answer
| | | | | | | | | |
✔true
T/F: Natural selection acts on individuals within a population - Correct answer
| | | | | | | | | | | |
✔true
T/F: Natural selection is the only factor that can lead to evolution - Correct
| | | | | | | | | | | | | |
answer ✔false |
T/F: Genetic drift (changes in allele frequencies due to chance alone) should
| | | | | | | | | | | |
have a greater impact in small populations - Correct answer ✔true
| | | | | | | | | |
Which of the following was true about Charles Darwin?
| | | | | | | |
A. He believed that evolution was due to the inheritance of acquired
| | | | | | | | | | | |
characteristics.
B. He supported Lamarck's explanation of how evolution occurred.
| | | | | | | |
, C. He observed that populations contain natural variation.
| | | | | | | |
| D. None of the above. - Correct answer ✔C
| | | | | | | |
Which of the following was NOT part of Darwin's theory of Evolution?
| | | | | | | | | | |
| A. Natural Selection
| |
| B. Populations as the units of Evolution
| | | | | |
| C. Mutations as sources of genetic variation
| | | | | |
| D. Survival of those who produce more offspring - Correct answer ✔C
| | | | | | | | | | |
Founder of taxonomy - Correct answer ✔Linnaeus
| | | | | |
Believed that evolution from disuse of body parts and the inheritance of
| | | | | | | | | | | |
characteristics - Correct answer ✔Lamarck | | | |
Father of paleontology, opponent of evolution , extinctions occur - but through
| | | | | | | | | | | |
many catastrophes that wipe out species - Correct answer ✔Cuvier
| | | | | | | | |
Uniformitarianism - Correct answer ✔Earth changes gradually, allowed time | | | | | | | | |
for evolution to occur
| | |
Early geologists - uniformitarianism - Correct answer ✔Hutton & Lyell
