In the actual experiment the results appear somewhat more complicated because the hybrid cannot be distinguished from one of the original parents, but the results really conform exactly to the imaginary case given above. The accompanying diagram will make clearer the account that follows. A B ↘ ↙ ↘ ↙ A(B) ↙ | ↘ ↙ | ↘ A | B | A(B) ↙ | ↘ ↙ | ↘ A | B | A(B) ↙ | ↘ ↙ | ↘ A | B | A(B) The hybrid, _A_(_B_), produced by crossing _A_ and _B_ is like _A_ so far as the special character that we will consider is concerned. In reality the character that _A_ stands for is only dominant, that is, it has been inherited discontinuously, while the other character, represented by _B_, is latent, or recessive as Mendel calls it. Therefore, in the table, it is included in parentheses. If the hybrids, represented by this form _A_(_B_), are bred together, there are produced two kinds of individuals, _A_’s and _B_’s, of which there are three times as many _A_’s as _B_’s. It has been found, however, that some of these _A_’s are pure forms, as indicated by the _A_ on the left in our table, while the others, as shown by their subsequent history, are hybrids, _A_(_B_). There are also twice as many of these _A_(_B_)’s as of the pure _A_’s (or of the _B_’s). Thus the results are really the same as in our imaginary case, only obscured by the fact that the _A_’s and the _A_(_B_)’s are exactly alike to us in respect to the character chosen. We see also why there appear to be three times as many _A_’s as _B_’s. In reality the results are 1 _A_, 2 _A_(_B_), 1 _B_. In subsequent generations the results are the same as in this one, the _A_’s giving rise only to _A_, the _B_’s to _B_, and the _A_(_B_)’s continuing to split up into the three forms, as shown in our diagram. Mendel found the same law to hold for all the characters he examined, including such different ones as the form of the seed, color of seed-albumen, coloring of seed-coat, form of the ripe pods, position of flowers, and length of stem. Mendel also carried out a series of experiments in which several differentiating characters are associated. In the first experiment the parental plants (varieties) differed in the form of the seed and in the color of the albumen. The two characters of the seed plant are designated by the capital letters _A_ and _B_; and of the pollen plant by small _a_ and _b_. The hybrids will be, of course, combinations of these, although only certain characters may dominate. Thus in the experiments, the parents are _AB_ (seed plant) and _ab_ (pollen plant), with the following seed characters:— Seed parent {A form round Pollen parent {a form angular _AB_ {B albumen yellow _ab_ {b albumen green When these two forms were crossed the seeds appeared round and yellow like those of the parent, _AB_, _i.e._ these two characters dominated in the hybrid.
