You are studying a protein that you think functions as a protease. You know the genetic code and amino acid sequence for the protein and you hypothesize that a serine is critical to the enzyme's function. Describe an experiment or set of experiments that would test your hypothesis.

In guinea pigs, black fur (b) is dominant over white fur (b). cross a heterozygous (hybrid) black guinea pig with a homozygous (purebred) white guinea pig. complete a punnett square, identify the genotype(s), phenotype(s), and probability (% and fraction) that the offspring will be black and white?
