Population
|
The smallest unit of evolution

Microevolution
|
A change in allele frequencies in a population over generations
|
|
Genetice Variation
|
differences among individuals in the composition of their genes or other DNA segments
|
|
Discrete Characters
|
can be classified on an either-or basis

|
Average Heterozygosity
|
The average percentage of loci that are heterozygous

Geographic Variation
|
differences in the genetic composition of separate populations

|
Cline
|
a graded change in a character along a geographic axis
|
|
Conditions of Hardy-Weinberg Equilibrium
|
No mutations, random mating, no natural selection, extremely large population size, no gene flow
|
|
Hardy-Weinberg Equation
|
p2 + 2pq +q2 = 1
|
|
Population
|
A group of individuals of the same species that live in the same area and interbreed, producing fertile offspring
|
|
Gene pool
|
Consists of all copies of every type of allele at every locus in all members of the population
|
|
Genetic Drift
|
Chance events can also cause allele frequencies to fluctuate unpredictably from one generation to the next especially in small populations
