Getting to know the model

You have already used this model. Answer the questions below to refresh your memory.

Questions

Please answer the questions below.

If you set the values of homozygous-dominant-males to 100 and homozygous-recessive-females to 100, and all the other values of initial males and females zero, what would be the values of p and q? 

If you set the values of initial males and females as follows:

  • initial-homozygous-dominant-males: 50
  • initial-heterozygous-males: 100
  • initial-homozygous-recessive-males: 50
  • initial-homozygous-dominant-females: 50
  • initial-heterozygous-females: 100
  • initial-homozygous-recessive-females: 50

What would be values of p and q? 

What about the frequencies of AA, Aa and aa?

Do you think the model, in its current state, satisfies all the Hardy-Weinberg Law of Genetic Equilibrium conditions?

Run the model for 15 generations with the conditions in the previous two questions. Note your observations.

Do you think that the Hardy-Weinberg law holds?

Explain your answer to the previous question.
