A Brief Introductory Note

Back in late September of 2005, Squeaky Squad (Lisa Chen, Joe Lee, Prapti Shah, and Alison Rankin of Period One AP Biology) obtained a black spotted white male from a local pet store to breed with four albino females. Dubbed Moofish for his cow-like coloring, the variable mouse served as the basis of their entire experiment. Generations afterward would reflect different facets of Mr. Moofish's genome, since each litter would be bred with its sibling.
So intrigued by this mysterious coloring, Squeaky Squad began their quest on isolating the gene for fur coloring in mice by carefully documenting the offspring of subsequent generations.
