Document Summary
Compare and contrast questions- tell why they are similar and what makes them different not just de ne. Drawing these you see what parts are still there and then the dotted line is where the de ciency is. So you know the region that is missing in all three that overlaps in the one that is causing long life. To verify this we use a method called quantitative complementation. When crossed with a de ciency of a speci c trait. Something about the l and the s alleles are different. We need to look at dna sequence polymorphisms ( functional polymorphisms not r ps, rpds, etc. ) Dna sequence is the ultimate view of standing genetic variation! Signatures of past evolution are contained in dna sequences. In the 1960"s was formed the neutral theory ! Deviations from the neutral theory shows deviations in selection, demographic events such as drift, bottleneck, and founders effect.
