AP Biology Lab 3: Comparing DNA Using BLAST ESSAY 2009 Phylogeny is the evolutionary history of a species. (a) The evolution of a species is dependent on changes in the genome of the species. Identify TWO mechanisms of genetic change, and explain how each affects genetic variation. (b) Based on the data in the table below, draw a phylogenetic tree that reflects the.
AP Bio - Hardy Weinberg Lab Background: G.H. Hardy and W. Weinberg developed a theory to track the evolution within a population based upon allele frequencies. In this experiment a theoretical population's ability to taste the chemical PTC (phenylthiocarbamide) is being tested.
