speciation through isolation
patters in evolution
100
the combined alleles of all individuals in a population
What is gene pools
100
the observable change in the allele frequencies of a population over time
What is microevolution
100
when individuals move between populations
What is gene flow
100
occurs when members of different populations can no longer mate successfully with one another
reproductive isolation
100
evolution toward similar characteristics through unrelated species
What is convergent evolution
200
is a measure of how common a certain allele is in the population
What is allele frequency
200
distribution in a population in which allele frequency is highest near the mean range value and decreases progressively toward an extreme end
What is normal distribution
200
change in allele frequencies due to chance alone
What is genetic drift
200
the rise of two or more species from one existing species
What is speciation
200
when closely related species evolve in different directions they become increasingly different
What is divergent evolution
300
a random change in the DNA of a gene
What is mutation
300
a type of selection that favors phenotypes at one extreme o a traits range is called directional selection
What is directional selection
300
genetic drift that occurs after an event greatly reduces the size of population
What is bottleneck affect
300
isolation caused by differences in courtship or mating behaviors
What is behavioral isolation
300
the process when two or more species evolve in response to changes in eachother
What is coevolution
400
a new allele combination formed in offspring through meiosis
What is recombination
400
the intermediate phenotype is favored and becomes more common in population
What is stabilizing selection
400
genetic drift that occurs after a small number of individuals colonize a new area
What is founder effect
400
involves physical barriers that divide a population into two or more groups
What is geographical isolation
400
the elimination of a species from Earth
What is extinction
500
The study of heredity and the variation of inherited characteristics.
What is genetics
500
occurs when both extreme phenotypes are favored
What is disruptive selection
500
occurs when certain traits increase mating success
What is sexual selection
500
when timing prevents reproduction
what is temporal isolation
500

Sharks and dolphins both have streamlined bodies that allow them to move through water efficiently, this is an example of which type of evolution?

Convergent
