Document Summary
Explained how genetic information is transmitted from one generation to the next. Genetics: the study of the inheritance of traits, the nature of genes, and how genes work. Heredity: the transmission of traits from parents to offspring via genetic information. Trait: any observable characteristic at any level of observation of an individual. Ranges from height to the primary structure of a membrane protein. Blending inheritance: proposed that the traits observed in the parents blend together to form traits in their offspring. Ex: black sheep and white sheep would have offspring with gray wool. Inheritance of acquired characters: proposed that traits present in parents are modified through use and then passed on to their offspring in a modified form. Ex: if giraffes extended their necks to reach high trees, they transmit that acquired trait to produce longer-necked offspring. Garden pea first model organism in genetics.
