Chromosomes And Sex

Indicates the use of the drosophila fly in the study of inheritance and describes T H Morgan's experiments with sex-linked inheritance. Depicts gene mapping on X and Y chromosomes, the sex determiners in man, Explains the use of drosophilia in the study of inheritance, and beginning with the work of T. H. Morgan, follows experimentations involving the genes on the sex chromosomes. Diagrams Morgan's experiments with drosophila showing criss-crossed and sex-linked inheritance. Maps the genes on the "x" and "y" chromosomes. Explains color blindness and hemophilia in man and eye color in drosophila. Illustrates gynander in a drosophila, a finch, and a bonellia worm. Concludes that the "x" and "y" chromosomes are all-powerful in determining the sex of a human being.NOTE: Two (or more) records have been merged together to create this data.
