4. Hardy-Weinberg Equilibrium:

  • Definition: The Hardy-Weinberg Equilibrium is a mathematical model used to study the genetic makeup of populations and test whether they are evolving. It states that allele frequencies in a population does not change from generation to generation.

  • Conditions for Equilibrium:

    • No mutations

    • No gene flow (immigration/emigration)

    • Large population size

    • Random mating

    • No natural selection

  • Significance: The Hardy-Weinberg Equilibrium helps scientists understand how and why populations may deviate from equilibrium and provides insights into the forces of evolution. It is used to study genetic variation within populations.
