i only have high school biology to go on here (s someone can correct me if im wrong), but i think it has to do with wwhich genes were dominat or carriers. if, for instance in humans, two people have the recessive gene for, say, albinosm, their babies COULD get it. this is because each parent contributes 2 "genes"= 4 altogether. a human only needs 2, so there are different combinations that could occure.. we did this experiment with rabbit colouring in high school :?
