Answer
The term "genetics" was coined by William Bateson in 1905. It is derived from the Greek word "genēs" (γένεσις), meaning "birth" or "origin", and "-ikos" (ικός), meaning "relating to". Bateson's definition of genetics was "the study of the phenomena of heredity and variation", and he saw it as a branch of biology that would help to explain the transmission of characteristics from parents to offspring.
