?Sex Limited Inheritance in Drosophila? (1910), by Thomas Hunt Morgan
In 1910, Thomas Hunt Morgan [4] performed an experiment at Columbia University [5], in New York City, New York, that helped identify the role chromosomes play in heredity. That year, Morgan was breeding Drosophila [6], or fruit flies. After observing thousands of fruit fly offspring with red eyes, he obtained one that had white eyes. Morgan began breeding the white-eyed mutant fly and found tha...

متن کاملSex-limited Inheritance and Abnormal Sex Ratio in Strains of the Housefly.
M A L E S of the housefly (Musca domestica L.) causing sex-limited inheritance of the mutants on the second chromosome have frequently been observed in strains of North American origin (SULLIVAN 1958, 1961; MILANI and FRANCO 1959; HIROYOSHI 1960, 1961). TSUKAMOTO, BABA and HIRAGA (1961) also found similar males in a strain from Japan. When those males were crossed to females carrying recessive ...
متن کاملSex, 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...
متن کاملFractional Populations in Sex-linked Inheritance
We study the fractional populations in chromosome inherited diseases. The governing equations for the fractional populations are found and solved in the presence of mutation and selection. The physical fixed points obtained are used to discuss the cases of color blindness and hemophilia. 87.10.+e, 42.62.Be Typeset using REVTEX
