COLOR INHERITANCE AND SEX INHERITANCE IN CERTAIN APHIDS

Sex, Sex Inheritance and Sex Determination in Paramecium Aurelia.

those produced by x-irradiation, the above result and further experiments producing mutations with neutrons may lead to new conclusions regarding the interaction of radiation ions with genes and hence of the size and structure of the gene. It is interesting to note that the ratio of effectiveness (5 or 6 to 1) for the effects on mature sperm of neutron as compared with x-irradiation is comparab...

The Inheritance of Shank Color in Chickens.

Several publications in recent years have given conflicting reports upon the inheritance of shank color. Yellow shank color has been reported to be inherited in a simple Mendelian fashion, the sex-linked gene for yellow shank color ( U ) being dominant to its allele (y) , the gene for blue shank color. In contrast to this, the gene for yellow shank color has been reported to be autosomal, the r...
