Etymology
Origin of geneticist
Explanation
A geneticist is a scientist who studies the traits that are passed from parents to their offspring. If you're fascinated with DNA, you might want to be a geneticist. Genetics is the branch of biology that focuses on genes, and it's practiced by geneticists. These scientists study the way genes are passed from one generation to the next, including how they vary or mutate. Some geneticists work with plants, improving their genetic resistance to disease or pests; others counsel patients who have inherited diseases or conditions. Geneticist is from genetics, originally defined as "pertaining to origins," from the Greek root genesis, "origin."
