Hardy-Weinberg Equilibrium
back
States that allele and genotype frequencies in a population will remain constant from generation to generation under certain/ideal conditions.
front
Frequency of the dominant allele.
back
What does p stand for?
front
Hardy-Weinberg Equation for Allele Frequencies
back
What is this equation called?
front
Frequency of the recessive allele.
back
What does q stand for?
front
Hardy-Weinberg Equation for Genotypic Frequencies
back
What is this equation called?
front
Frequency of the Homozygous Dominant genotype.
back
front
Frequency of the Homozygous Recessive genotype.
back
front
Frequency of the Heterozygous genotype.
back
front
Reproductive Isolation
back
Processes that prevent the members of two different species that mate from producing offspring, or which ensure that any offspring that may be produced are sterile.
front
Speciation
back
The formation of new and distinct species in the course of evolution.
front
Behavioral Isolation
back
An evolutionary mechanism that helps members of the same species identify each other as proper mates.
front
Geographic Isolation
back
Speciation that occurs when biological populations of the same species become isolated from each other to an extent that prevents mating.
front
Temporal Isolation
back
Isolation that occurs due to different mating schedules of organisms in a population. Over time, these differences may lead to speciation.
front
Convergent Evolution
back
Unrelated species develop similar characteristics.
front
Divergent Evolution
back
Related species develop different characteristics.
front
Coevolution
back
The influence of closely associated species on each other in their evolution.
front
Extinction
back
The end of an organism or of a group of organisms, normally a species.
front
Punctuated Equilibrium
back
The hypothesis that evolutionary development is marked by isolated episodes of rapid speciation between long periods of little or no change.
front
Adaptive Radiation
back
Diversification of organisms to fill different niches.
