Chapter 16 Check & Challenge


1. This would be more likely to produce Micro Evolution as it will affect individual organisms rather than big groups of organisms.
2. Gene pools are all the possible genes in a species while allele frequencies are for individual environments.
3. Gene pools are more localized and so they must be relating to populations rather than to species.
4. Mutations affect a species really quickly while genetic recombination takes time.
5. It predicts that the allele frequencies will stay the same over time.



1. It is the most important in the small populations as it has a bigger effect the fewer amount of organisms present there.
2. The main forces that affect gene pools are natural selection as it is when organisms with weak adaptations are eliminated and organisms with strong adaptations survive.
3. It has the same chance of occurring each time but it increases exponentially to happen more than once.
4. The studies of twins are more important for studying quantitative traits as there are many alleles which may affect these.


Reviewing Ideas

1. A gene pool is the total genes in a population.
2. Shape and color.
3. Natural Selection does not play a role.
4. Natural Selection is the survival of the fittest.
5. Artificial selection picks the genes while natural selection has the best genes continue.
6. The color of their wings and the colors of the trees.
7. There is not enough treatment for the disease in some areas.
8. The original source is a mutation.
9. Genetic Drift is a small change.
10. It states that if an area starts with just one allele, a new one can not be present.
11. A line of closely related organisms that breed.
12. Internal Factors and the Environment.
13. Identical twins have the same DNA Fraternal Twins have different DNA.


Using Concepts
1. I think that it would become more and more recessive to the point where it dies out.
2. An open pollinated plant as it can mix with many different plants.
3. This adaptation prevents inbreeding and can help save lives because it does not pass on one of the deadly alleles.
4. I would breed them through trees and make sure they do not inbreed
5. There are not many ways for animals to get to islands.
6. Because evolution takes a long time.
