natural selection and genetic drift

[imraan47]

Hey guys.

i am having great trouble interpreting the simulation of genetic drift and natural selection...the links are http://darwin.eeb.uconn.edu/simulations/drift.html
and
http://darwin.eeb.uconn.edu/simulations/selection.html
respectively.

I am supposed to provide results and compare the 2 simulations.
The professor said that the effort and amount of thinking are the main determinants of the mark.

I have played with the graphs for a few days but havent figured out much. If anyone can kindly help me out, that would be much appriciated.

Does this help?

one the main lessons here is that the an allele drifts quicker to dominance in smaller populations, which similarly allows for quicker fixation of neutral alleles in smaller populations than in huge populations.

Helps just a little. Somehow i just cant seem to get the concept and have read about genetic drift and natural selection.
