Inheritance in
Ricinus communis L. Part IIFactors
M andB are linked, there being 8.3 per cent. cross-overs in the back-cross ofF 1 by double recessive.Factors
G andB are independently inherited.Factors
M andG are independently inherited.The relation between
S andG is somewhat obscure, the percentage of cross-overs in the back-cross of F1 by double recessive being considerably greater than the percentage of non-cross-overs. -

Crosses of Crinkled Dwarf × Sea Island exhibit complete dominance of Sea Island, but in crosses with other Peruvian types, dominance is slightly disturbed, producing in
F 1 normals with a slight trace of crinkling and some variation of the Crinkled class inF 2.A cross of Crinkled Dwarf × Upland gave an intermediate
F 1 with dominance becoming increasingly manifest in back-crosses of heterozygote to Upland.Selfed heterozygotes from the first back-cross produced in one case a family indicating true reversal of dominance, the ratio 3 Crinkled: 1 normal being obtained. Reversal of dominance persisted in the next generation from this family.
Crosses involving Crinkled and
G. sturtii gaveF 1 strongly crinkled, but a heterozygous Crinkled ×G. sanguineum gaveF 1 only slightly crinkled.The bearing of the experiments on Fisher’s theory of dominance is discussed, and it is concluded that while the behaviour of Crinkled in Upland crosses is in accordance with the Fisher theory, the process by which genes modifying dominance are thought to have become homozygous in Peruvian involves the assumption that normals descended from heterozygotes have replaced the original normal population. This assumption is thought to be improbable.

The genetics of cotton - Part VI. The inheritance of chlorophyll deficiency in new world cottons
The occurrence of relative chlorophyll deficiency in crosses between
G. barbadense andG. hirsutum is shown to be dependent upon three pairs of factors, probably independently inherited, which are designated as follows:Modifying factors considerably affect the distribution of chlorophyll deficiency in the chlorophyll-deficient class, and within it was found a range from completely lethal to fully viable.
The distribution of the chlorophyll-deficient factors was investigated in
G. barbadense, G. hirsutum andG. tomentosum. G. barbadense carried only Cha.G. hirsutum always carried Chb, but Chc was found in all three phases of the gene—ChcChc, Chcchc and chcchc.G. tomentosum carried the combination Cha and Chb.
