[16] Kammerer's chief papers on this subject are Archiv fur Entwm., XVII, 1904, and ibid., XXV, 1907. An epitome of results is also given by him in 12 Flugschrift d. Deutsch. Ges. f. Züchtungskunde, Berlin, 1910.

Züchtungkunde, Berlin, 1910, p. 26. In the paper in Mendel Festschrift, 1911, the subject is continued, but no more is added as to this part of the experiment.
