What are the 5 conditions for the Hardy Weinberg principle and what is required for?

The Hardy-Weinberg model states that a population will remain at genetic equilibrium as long as five conditions are met: (1) No change in the DNA sequence, (2) No migration, (3) A very large population size, (4) Random mating, and (5) No natural selection.

What are the 5 principles of the Hardy-Weinberg equilibrium quizlet?

Terms in this set (5)

  • No mutations. The gene pool is modified if mutations alter alleles or if entire genes are deleted or duplicated. …
  • Random mating. …
  • No natural selection. …
  • Extremely large population size (no genetic drift) …
  • No gene flow (emigration, immigration, transfer of pollen, etc)

What is the Hardy-Weinberg principle used for?

The Hardy-Weinberg equation is a mathematical equation that can be used to calculate the genetic variation of a population at equilibrium. In 1908, G. H. Hardy and Wilhelm Weinberg independently described a basic principle of population genetics, which is now named the Hardy-Weinberg equation.

What does the letter Q stand for in the Hardy-Weinberg equation?

In the Hardy- Weinberg equation, the letter q stands for homozygous recessive alleles.

What is genetic drift example?

Genetic drift is a change in the frequency of an allele within a population over time. A population of rabbits can have brown fur and white fur with brown fur being the dominant allele. … By random chance, the offspring may all be brown and this could reduce or eliminate the allele for white fur.

What are the conditions for Hardy-Weinberg equilibrium?

The conditions to maintain the Hardy-Weinberg equilibrium are: no mutation, no gene flow, large population size, random mating, and no natural selection. The Hardy-Weinberg equilibrium can be disrupted by deviations from any of its five main underlying conditions.

What is the Hardy-Weinberg principle quizlet?

Hardy-Weinberg Principle states. principle that allele and genotype frequencies in a population will remain constant unless one or more factors cause the frequencies to change. Hardy-Weinberg formula. p² + 2pq + q² = 1 ; can be used to determine if a populations is in genetic equilibrium.

What are the 6 patterns of evolution?

There Are Six Important Patterns of Macroevolution:

  • Mass Extinctions.
  • Adaptive Radiation.
  • Convergent Evolution.
  • Coevolution.
  • Punctuated Equilibrium.
  • Developmental Gene Changes.

What are the 4 mechanisms of natural selection?

The Hardy-Weinberg equilibrium principle says that allele frequencies in a population will remain constant in the absence of the four factors that could change them. Those factors are natural selection, mutation, genetic drift, and migration (gene flow).
