natural selection
What is another way to describe natural selection?
survival of the fittest
What are the four bases of mutation
A, C, G, T
How does frequences change?
By chance
What is migration?
Migration is a powerful mechanism for equalizing the gene frequencies of subpopulations in a species in the absence of selection.
Who discovered natural selection?
Charles Darwin
How many types of mutations are there?
three types of DNA Mutations: base substitutions, deletions and insertions.
Why genetic drift occurs in small population?
in small populations allele frequencies are likely to change rapidly and dramatically over very few generations or drift because of random events.
How does migration affect gene flow?
modifying allele frequencies
What is the theory of Natural Selection?
Organisms that are more adapted to their environment are more likely to survive and pass on the genes that aided their success.
where do mutations occur?
In our DNA
Can genetic drift cause a new population to be genetically distinct from its parent population?
Yes
How does migration affect evolution?
Migration will generally unify gene frequencies among populations rapidly in evolutionary time.
