Abstract: There are many poultry problems awaiting the trained geneticist. In fact there has developed a condition in which progress in other fields of poultry research is being arrested by the inactivity of the geneticist. The nutrition worker is encountering a disconcertingly wide range of variability in resistance to inadequate diets. There is now evidence that crookedness of the breast bone, which frequently has been used as a diagnostic feature for rickets, may be due to inherent factors. Although the problems in incubation are largely physiological there is need for study of genetic factors involved before basic studies may be far pursued. Thus three major fields of investigation await the cooperation of the geneticist for the solution of their problems. The superficial characteristics of poultry, although of no practical significance must first be analyzed to form a basis for study of physiological characters such as fecundity, egg size, etc. Through linkage . . .
