solve questions 1,2,3. Are my answers correct?

ade on october 17 by Sarah S Please hand in work on a 5 x 11 inch paper Place name on each sheet Use the selection and mutation model found in the Populus program to answer questions 1-3 below See figure below for example of input screen s selection coefficient, and u mutation rate of A to a Starting frequency refers to the frequency of p. I Selection B Mutation Input 0.65 0.1 1 Assuming an initial frequency of p 01 and s and u- (0.0 and 1 0 x 10 respectively), what happens to the requency of p over time? is mutation alone, a strong force of selection? The frequency ofpstays constant over time (in equnbrium ion alone is not a strong force 2 Repeat question one above s and v 1005 10 x 101, respectively) and the same frequency of How does this dage the outcome of the mode? using the same and of values, run the smulaton with p s lo g 06 5.0 How does this change the outcome the model?

Explanation / Answer

1. p stays in equillibrium as the selection coefficient is neutral.

2. yes , there is a gradual increase in p. over generations as s= 0.05. The selection coefficient is positive.

3. If the population is favoured there will be a slow increase intially like a small horizontal line then it will start increasing gradually for some generations and it remains constant again. If the population is not favoured by selection the curve decreasesand reaches zero of the x- axis.
