Summary of Event
In the 1920’s, the field of genetics had progressed to the point of locating hereditary information within the cell. Genes, which were uncharacterized elements responsible for the inheritable traits of organisms, had been localized to the chromosomes of cells. In the cells of higher organisms, multiple chromosomes are found...
