Document Summary
Gregor mendel used garden peas to work out rules of inheritance. Walter sutton and theodor boveri proposed chromosome theory of inheritance. Explains how genetic information is transmitted from one generation to the next. Asserted that genes are located on chromosomes. Genetics is the branch of biology that focus on inheritance. Heredity is the transmission of traits from parents to their offspring. A trait is any characteristic of an individual. At his time, 2 hypothesis had been formulated. Blending inheritance - parental traits blend so that their offspring have intermediate traits; offspring"s phenotype is a combination of mom and dad. Inheritance of acquired characteristics - parental traits are modified through use and then passed on; physiological changes acquired over the life of an organism may be transmitted to offspring. A species used for research; practical to work with; conclusions drawn from them can be applied to other species. Mendel chose peas as the model organism because.
