Summary
Progeny analysis showed that yellow-flowered chrysanthemum sports with carotenoid only in L1 are indistinguishable from their white progenitors in breeding behaviour; those with carotenoid in L2 breed quite differently. Chimerical structure has, therefore, to be considered when analysing flower colour inheritance data. Segregations were consistent with the action of the single dominant gene I. Such simply inherited characters may be useful in studies to distinguish between the several alternative patterns of inheritance which can be suggested in the species.
