Natural Selection
After his trip around the world with an important stop in the Galapagos, he wrote the book "On the Origin of Species by Natural Selection"
Who is Charles Darwin?
Directional selection would cause the average moth in 1800's England to become...
What is darker?
Movement of new allele from one location to another.
What is gene flow?
This is what we call all the alleles in a population
What is the gene pool?
Cladograms show these between species.
What are evolutionary relationships?
Each species has some of this and it increases the chances that at least someone in the species survives when the environment changes.
What is variation.
The type of selection when the average of a trait becomes more common.
A new allele coming from a change in DNA sequence.
What is a mutation?
This is what we call it when the allele frequency of a species changes?
What is evolution?
The name for a group of population who are reproductively isolated from other populations.
What is a species?
Natural selection over long periods of time can result in the evolution of new ...
What are species?
What is disruptive selection?
A change in the gene pool due to random chance.
What is genetic drift?
This is the how you calculate allele frequency.
What is (# of alleles/# of alleles in the gene pool)?
An ancestor and all its decendents are known as this.
What is a clade?
Natural selection will produce these traits that make it fit better into their environment.
What are adaptations?
Selection can result in a change in the frequency of these.
What are alleles?
When an individual gets to reproduce more, not because they are more fit, but because they're sexually attractive.
What is non-random mating (or sexual selection)?
This number would be the allele frequency of a gene pool if it were the only allele.
What is 1?
How many "cuts" can you make to a cladogram to describe a clade?
What is one?
When individuals are well matched to their environment and reproduce more than others we call it this.
What is fitness?
Selection picks these things that fit best into the environment to reproduce.
What are phenotypes?
What is the bottleneck effect?
Every member of the population (100) is heterozygous (Rr). There are only two alleles in this gene pool. What is the allele frequency of the dominant allele (R)?
What is .5?
Each branching point in the cladogram represenents this.
What is a speciation event?
