China's racing community also inquires, if Mongolian ponies are crossed by other equine breeds, do their progeny always bear evidence of such crossing amd if so what is the evidence to be looked for. The reply to the first part of that question is, that if two distinct breeds of animals of the same species be mated together some characteristics of each breed will appear in the progeny, but if this first generation be interred, then their progeny may be again a mixture or may revert to one or the other breed of the first cross. The reason why this occurs is follows animal is but a mass of microscopic cells amd these cells are of two varieties viz., those that compose the body (Somatic cells) and those that effect the continuation of the species (germ cells). From generation to generation there is no solution of continuity of the germ cells, one generation of germ cells is directly formed from the previous generation, and these cells may be considered to be a living cell passed in a living condition from parent to offspring. These germ cells contain a specific number of bodies (in the equine family twenty-six) known as chromosomes and these chromosomes are the bearers of all characters both racial and physical. During the process of becoming mature the germ cells of either sex lose half their number of chromosomes but when the germ cell of the male fuses with the germ cell of the female (the two cells join to become one cell) the specific number (26) of chromosomes are thus restored. It therefore must and does follow that as the chromosomes are the bearers of. all characters certain locations on the living' anima i characters of both sire and dam
