thats quite easy
the first pair always goes on the left. and the second pair goes on top. its like multiplying witu exponents. but this as an example , look at my first box. one capital L on top and the other on the left you put them together. if its capital and lowercase the capital one always goes first then its the lowercase (Ll). parent genotypes are the the two pair given to you.thr offspring genotype is the percent of the kids in the boxes. hope i helped!(:
