Understand that selection pressures acting on the gene pool change allele frequencies in the population, including:
- stabilising selection maintaining continuity in a population
- disruptive selection leading to changes or speciation.
Understand that selection pressures acting on the gene pool change allele frequencies in the population, including:
Understand that sometimes changes in allele frequencies can be the result of chance and not selection, including genetic drift.
Understand that allele frequencies can be influenced by:
Understand how the Hardy-Weinberg equation can be used to monitor changes in the allele frequencies in a population.
