Document Summary
Can think of molecular markers as an internal natural tagging system. Monarch: once tag goes on a butterfly it identifies an individual. Birds: can put on a band for an individual. Polar bear: can put on collar for individual. 1999: set up barbed wire with meat as attractant so that it would pull hair. Hair follicles contain cells and dna. Aggressive grizzly bear = play dead. Aggressive black bear = make lots of noise and be aggressive back. Species id: grizzly bears have a 13- 15 bp deletion in the mitochondrial control region when compared to the black bear. Gender id: used 2 genes zfx/zfy and sry (sex determining gene in animals, will only be found in males. ) When we amplify this gene we only expect to see it in the males. The problem with only using sry is the pcr may not work because of human error.
