Aleiulelism thusenables a breeder to place a correct value onpedigree. In mating up pens the general advice givenis that no two birds which have the same faultsshould be mated together, but that when onehas a prominent fault the mate sliouki be strongon that point. This general advice is un-doubtedly good and sound, and Mendelismexplains hov and why it works, and further itshows us how to utilise birds in future breeding. o -^ O ^ en -S Q s Z a 8 THE BOOK OF POULTRY. operations when the parental Omits appear intiicni.

So far breeders havenot hesitated to use such birds for explains such an appearance andalso shows us how pure rose-comb birds can bebred from .such a one.
