Hello, I was having troubles figuring tis question out. I understand that you must devise your own fitness matrix model, however, I wasn't sure what it meant by "assume that the a allele is selected for, and the the B and b alleles are selectively neutral.

This question requires the use of the "Populus" program online and the selection is on Model > Natural Selection > Two Locus Selection.

Help would be greatly appreciated, thank you.

(3) (10 marks) Devise a two-locus fitness matrix to model the genetic hitchhiking of a neutral gene on a selected locus. For example, assume that the gallele is selected for, and that the B and b alleles are selectively neutral. Here we are interested in how the frequencies of the B and b alleles change when there is selection on a. How closely these loci are linked (i.e. the value ofr) will clearly have an important effect on the allele frequencies and D. Explore the properties and the effects of this hitchhiking using the populus two-locus program. BB Bb bb Run this for some different values of r. Submit some plots and a summary table as you like. Explain in words what you have found out. (3) (10 marks) Devise a two-locus fitness matrix to model the genetic hitchhiking of a neutral gene on a selected locus.
