Hardy-weinberg Principle

Hardy-weinberg Principle

What is it?

A large randomly mating population without mutation, migration or selection keeps allele frequencies constant; deviations help identify evolutionary forces.

In simple words

• A large randomly mating population without mutation, migration or selection keeps allele frequencies constant; deviations help identify evolutionary forces.
• Understanding hardy-weinberg principle connects structure, mechanism and biological outcome. It helps explain how a change at one level can affect the whole organism, population or environment.
• A complete answer on hardy-weinberg principle links the starting condition to its mechanism and outcome.

Important terms

Hardy-Weinberg principle: A large randomly mating population without mutation, migration or selection keeps allele frequencies constant; deviations help identify evolutionary forces.

Mechanism: Start with the trigger or starting condition, follow the biological structures and signals in order, and finish with the response or product. For hardy-weinberg principle, the central relationship is: A large randomly mating population without mutation, migration or selection keeps allele frequencies constant; deviations help identify evolutionary forces.

Biological significance: Understanding hardy-weinberg principle connects structure, mechanism and biological outcome. It helps explain how a change at one level can affect the whole organism, population or environment.

What you should learn

• Define hardy-weinberg principle in accurate biological language.
• Explain the mechanism or relationship involved in hardy-weinberg principle.
• Apply hardy-weinberg principle to a comparison, prediction or Federal Board exam question.

Examples

• Identify the starting condition
• Name the active structure or molecule
• Trace the direction of change
