The study of evolution from a genetic point of view

• population genetics

• microevolution

• gene pool

• allele frequency

the total genetic information available in a population

• population genetics

• microevolution

• gene pool

• allele frequency

determined by dividing the number of a certain allele by the total number of alleles of all types in the population

• population genetics

• microevolution

• gene pool

• allele frequency

The genotype frequencies in a population tend to remain the same from generation to generation unless acted on by outside influence

• phenotype frequency

• hardy-weinberg genetic equilibrium

• gene pool

• allele frequency

One of the five assumptions of Hardy-Weinberg genetic equilibrium

• No net mutations occur

• Population does not produce offspring

• population is made up eukaryotic organisms

• equal rate of immigration and emigration

One of the five assumptions of Hardy-Weinberg genetic equilibrium

• populations have a surplus of food

• Individuals neither enter nor leave the population

• populations migrate as a herd

One of the five assumptions of Hardy-Weinberg genetic equilibrium

• Organisms have more than one offspring

• the population are carnivores

• The population is large

One of the five assumptions of Hardy-Weinberg genetic equilibrium

• Individuals mate randomly

• Females pick the strongest males to mate

• Males fight each other to mate with females

One of the five assumptions of Hardy-Weinberg genetic equilibrium

• Natural selection only occurs on the youngest in a population

• Naturals selection does not occur

• Natural selection only affect the weakest in the population

Why is genetic drift not a type of natural selection?

• It's random; not due to advantages that the individual has

• It's due to the environment, rather than chromosomal changes

• Humans are involved, making genetic drift artificial selection
