The number of copies of a specific version of a gene divided by the number of copies of all versions of that gene. This number can be used to show the amount of biological diversity in an individual, a population, or a species.
The number of births per 1,000 individuals in a population each year.
The maximum population size that can be supported over time by a given environment.
An interaction between groups of organisms. Each group tries to gain access to a resource that is low in quantity, such as food, mates, or shelter.
The number of deaths per 1,000 individuals in a population each year.
A factor that has more of an effect when there are more members of a population
A factor that is not afflected by increasing population.
The act of leaving one country or place to live in another.
Growth that occurs in an ideal environment, where the population size of an organism increases at a constant rate.
All of the alleles in a population
p^2+2pq+q^2=1, where p is the dominant allele frequency, q is the recessive allele frequency and p+q=1.
The state of a population in which allele frequencies do not change over time. This would be a non-evolving population.
The act of entering one country or place, from another to live.
The standard model of population growth in which a population exponentially increases until it levels off at its carrying capacity.
The percentage a physical trait appears in a population.
The study of how populations' genes are passed down from generation to generation.
