Inheritance of Aleurone Color. INHERITANCE OF ALEURONE COLOR. 69 the dual nature of the oxydases necessary for the formationof the color compounds. It is quite likely that the color in thealeurone cells of maize is similar in nature to flower color; and,as we fully agree with Miss Whedales conclusions, none of ourfactors C, R and P are to be regarded as chromogens. Theargument above is in agreement with this viewpoint. If onewishes to denote a chromogen, the addition of an X to representit, common to both families, makes no difference in the inter-pretation of the results. If we are dealing with a di-hybrid ratio, one pure purple earout of every nine should be expected in the F2 21a and 21b show that one such ear was obtained outof seventeen ears. If the total purple seeds and the sum of theparticolored and white seeds is consid
