Charles Darwin is noted for his theory of what? (hint: it's TWO words) |
Natural Selection |
|
|
Charles Darwin went on a sail on the Beagle and discovered his evidence for evolution on the Galapagos Islands. What was his evidence? |
The large differences between the same species that inhabited different islands. |
|
|
What can the Hardy-Weinburg principle and equation be used for? |
It can be used to show if a population is evolving/what is causing. The equation can even be used to estimate how many organisms in a population are carriers of a disease or have it. (Not completely accurate because always evolving.) |
|
|
The hash-marks on an evolutionary tree show what? |
Everything after those hash-marks has a certain trait. |
|
|
What is tay-sachs disease? |
It is a fatal hereditary disease that forms an abundance of lipids in the brain. Usually occurs in infants. |
|
|
Fossil records are very useful, as they can show the past changes of a species. Basically, they can show what? |
Evolution through the ages. |
|
|
Most vertebrates have tails or tail bones. This is an example of |
Homolgy/homologous structure. |
|
|
Organisms don't evolve. |
Populations do. |
|
|
Name a few rules about natural selection that are important to remember. |
It does not create new alleles or the perfect organism, it affects populations, not singular things, and only affects heritable traits to name a few. |
|
|
What are some types of selection? |
Disruptive selection, directional selection, artificial selection, sexual selection, stabilizing selection, and balancing selection. |
|
|
What is the bottleneck effect? |
The bottleneck effect is something occurring to drop a population drastically, causing genetic variation to be much less. |
|
|
What is the founder effect? |
The founder effect is some individuals moving to a new area and forming a new population that has different variation from the previous population. |
|
|
What is relative fitness? |
The contribution an individual makes to the gene pool in comparison to other individuals'. |
|
|
What are the five rules for a population's gene pool to remain the same throughout generations? |
1. large population 2. no inter-population mixing 3. no mutations 4. must have random mating 5. no natural selection |
|
|
What never happens naturally? |
The Hardy-Weinburg principle. |
|
|
What is the Hardy-Weinburg Equation? |
p^2 + 2pq + q^2 = 1 |
|
|
What is the heterozygote advantage? |
Recessive alleles can be protected from natural selection by "hiding" with dominant alleles. |
|
|
Hey. Guess what. |
You are gonna do well on this test. |
|
|
Hey have a great day. |
Yes I am telling you what to do deal with it. |
|
|
My cat loves you. |
So does my dog, for you dog people out there. |
