Pigs, cows, sheep, deers, chickens, and skate fish will be compared via protein electrophoresis to reconstruct a phylogenetic tree.
Protein electrophoresis is a technique that compares electrophoretic properties of proteins from different organisms (Brown et al, 2002). The results from this technique can be used to determine similarity between different organisms. Morphological traits may sometimes be used to reconstruct a hypothetical phylogenetic tree, but the morphological traits are not sufficient to determine phylogenetic relationships. Using a similarity matrix derived from the electrophoresis gel, a more accurate set of relationships can be drawn.
