All the members of a single species occupying an area at the same time.
Total of all the genes of all the individuals in the population.
Any evolutionary change at or above the species level.
Occurs when there is a change in the allele frequency of genetic characteristics within a population.
Gene Mutations
Chromosome Mutations
Recombinations
Occurs when a small number of individuals, representing a fraction of the original population, found a colony and only certain of the original alleles are passed on.
When a population is subjected to near extinction due to natural disaster, hunting, and loss of habitat.
Which is NOT a requirement of natural selection?
Occurs when the environment is changing.
Phenotype selected: extreme over the average
Occurs when the environment is stable (constant)
Phenotype selected:average
Phenotype selected: 2 extremes
Gamete mortality
Zygote mortality
Hybrid sterility
F2 Fitness
Occurs when populations diverge from one another to the extent that members of 1 population are no longer capable of successful reproduction with members of another population.
Populations seperated by geographic barriers that prevent them from reproducing
Members of a single population develop a genetic difference that prevents them from reproducing with the parent type
