Preview - Hardy Weinberg Population Genetics

Case I


Procedure Need to take initial readings as well to compare and totals are important.

Using the Net Logo Hardy Weinberg model you will run a simulation of a population of randomly heterozygous individuals with an initial gene frequency of 0.5 for the dominant allele (A) and the recessive allele (a).

  1. Before moving on spend 5 minutes familiarizing yourself with how the model works by... 
  2. Set up your population size to 500.
  3. On the bottom left side of your simulation set your max- generation to 100.
  4. Select the species you would like to observe... turtles, humans, etc...
  5. Click on the “set up” button.
  6. Collect initial data in the data table before moving on.
  7. Click on “go.”
  8. Monitor the population closely by observing the species and graphs (genotype, phenotype, and allele)
  9. Analyze the data after 100 generations and complete the table below.

Thank goodness for computer simulations!

 

 

 


Questions

Please answer the questions below.

What trend do you observe for the genotype frequency?


What trend do you observe for the phenotype frequency?


What trend do you observe for the allele frequency?


What does the Hardy Weinberg equation predict for the new p and q?


Do the results you obtained in this simulation agree? If not, why?
