In an attempt to determine all the genes involved in hair color in guinea pigs, you identify four lines of true-breeding guinea pigs (hair is normally brown in this type of guinea pig). Shown in the table below are the resulting phenotypes of the offspring from your complementation test, in which you crossed the fourguinea pig lines in all possible combinations: (+) represents normal brown hair color, (-) represents white hair. 23 1 2 3 4 0 1 02 O 3 04 1 0 1 and 2 1 and 3 + O2 and 4 O2 and 3 1 and 4 3 and 4 - + 4 + Part 1 How many different genes are represented in these four lines of guinea pigs? + + Part 2 Which lines are actually defined by a mutation in the same genes?
