The definite proportion of one to three is said by those scientists who devote themselves to heredity to be “as fundamental to a right understanding of heredity as the law of definite proportions in chemistry.” It applies to guinea pigs, mice, rats, and rabbits as uniformly as it applies to the garden flowers. And one of the results of scientific observation of the development of hereditary traits in these little animals points to an explanation which would undoubtedly have deeply interested the Austrian pioneer in his flower garden. The characteristic of color, green or yellow, in the peas with which he was experimenting was resident not in the flowers themselves but in the germinal material which formed the seed leaves of these flowers; and the germinal material of a yellow seed
