Excerpt from The Popular Science Monthly, Vol. 84: January to June, 1914 T is generally recognized to-day that the central idea of, Mendel's discovery in regard to heredity is that when two contrasting ele ments enter a hybrid, one from each parent, they separate in the germ cells of the hybrid, so that the germ - cells are pure like those of the orig inal parents in regard to each element.1 Chance meetings of the germ cells give the ratios that are characteristic of Mendelian heredity. This is illustrated by the example that Mendel gave. When a pea having green seeds is crossed with a pea having yellow seeds a hybrid pea is produced. When the germ-cells of the hybrid are ripened, each ovule carries either the element for green or that for yellow, but never both. Yellow and green have separated. The same separation occurs in the formation of the pollen. If self-fertilization now takes place chance combinations of the yellow or green-bearing ovules with the yellow or green-bearing pollen give one pure yellow pea, two hybrid (yellow) peas, one pure green pea, as shown in Fig. 1.
