Document Summary
Population genetics iii: natural selection, linkage disequilibrium and association mapping. Interaction of forces (forces that effect allele frequency of a population of a given. The forces of evolutionary change gene, allusion= change of allele frequency?) natural selection: mutation, migration genetic drift. Bats are nocturnal animals, with an adaptation of echolocation. Bullshorn acacia=a tree that goes in the tropics that is very palatable to mammals, but its adapted to live with ants, providing a home for them, the ants live in the home and get food from it. Nematode parasite that an ant gets a berry on its ass, bird eats this berry like ant, and the parasite gets into the birdie. They used to use the light on the surface as the tree as camouflage. In the middle of the 20th century, the trees they were chilling on was darkened by coal in the industrial revolution. White phenotype was now exposed to predators, and dark was preferably selected.
