Natural Selection
What process causes individuals with favorable traits to survive and reproduce more successfully?
What is Natural Selection?
Structures that are similar because of shared ancestry are called these.
What are Homologous Structures?
This principle states that allele frequencies remain constant if evolution is not occuring.
What is the Hardy-Weinberg Principle?
What is Speciation?
What is a Phylogenetic Tree?
There are inherited characteristics that improve an organism´s survival.
What are adaptations?
The preserved remains or traces of ancient organisms are called these.
What are Fossils?
In the equation p2 + 2pq + q2 = 1, what does p represent?
What is the Frequency of the Dominant Allele?
When two populations are separated by a physical barrier, this type of isolation occurs.
What is Geographic Isolation?
The point where two branches split on a phylogenetic tree represents this.
What is a Common Ancestor?
This scientist proposed evolution by natural selection after studying finches.
Who is Charles Darwin?
Similar embryonic development among species supports this biological idea.
What is Common Ancestry?
What is:
- No Mutations
- Large Population
- Random Mating
- No Natural Selection
- No Gene Flow
Speciation occurring without geographic separation is called this.
What is Sympatric Speciation?
Random changes in allele frequencies are called this.
What is Genetic Drift?
When individuals in a population vary in traits, this is called___.
What is Genetic Variation?
Structures with similar function but different ancestry are called these.
What are Analogous Structures?
If a population is not in Hardy-Weinberg equilibrium, what is occuring?
What is Evolution?
Different mating seasons between species is an example of this type of reproductive isolation.
What is Temporal Isolation?
Movement of alleles between populations is called this.
What is Gene Flow?
A sudden environmental event greatly reduces population size and genetic diversity. This is known as what effect?
What is the Bottleneck Effect?
This field compares DNA and protein sequences to determine evolutionary relationships.
What is Molecular Biology?
A small group starting a new population with different allele frequencies is called this effect.
What is the Founder Effect?
When hybrid offspring are sterile, this is an example of what type of barrier?
What is Postzygotic Isolation?
Natural selection that favors individuals at both extremes of a trait is called this type of selection.
What is Disruptive Selection?
