Genetic distance measures

Up to Week 3: Gene flow measurements: what, where, how many

Genetic distance measures

Posted by Melanie Murphy at March 11. 2009

Hi Lisette -




I mentioned this in one of the other comments, but it would be extremely helpful to have a slide/table that talks about the assumptions of genetic distance measures (HW, mutational model, etc). 




Also, it looks like both Sam and I will be talking about proportion of shared alleles.  It can be calculated at both pop level and individual level.  Would it be too much trouble to add it to the lecture?  Dps does not make any assumptions of HW or linkage eq, so is useful in cases of recent population change.  I can explain it in my lecture if needed, but seems appropriate to mention it here.




For alleles in space, is it worth-while to mention how spatial locations area assigned to the midpoint of the vector connecting sites?



I think assignment tests fall nicely into the next lecture.  Maybe give a brief introduction alluding to the next lecture?

I just finished reading thru all the other slides so yes, I'll add the genetic distance measures and a slide about assumptions (if you already have something made up let me know). 



concerning the assignment test stuff.  are you suggesting that it goes in Stephanie's defining populations or Dyer's measure direct gene flow?  I was thinking if we moved Dyer's lecture after my gene flow lecture as you and I are suggesting...he could start with the plant specific stuff and I can then end with assignment tests as the more commonly used "direct gene flow" method with animals...then that would flow right into Stephanie's defining populations.  Since assignment tests were orginally applied to defined populations I thought that simplier concept should be clearly introduced before we get to defining populations using bayesian clustering.  And stephanie has a whole lot to cover in her lecture.



What do you think of this proposed change?
