Answer:
C)The geneticist focuses on what causes the disease, and the orthopedist treats the disease.
Step-by-step explanation:
A researcher who works in the field of genetics is called as geneticist. Geneticists are the professionals who find out the cause of a genetic disease, the molecular mechanism behind the disease and find out the ways to cure the disease by carrying out various experiments in laboratory. The nature of the gene and how it controls the growth of a bone will be studied by the geneticists only. All these things are a part of research which is performed by researchers.
Once the geneticists have completed the research work, then after role of a orthopedist (doctor) comes into picture. A doctor is a professional who is qualified in medicine and an orthopedist is a doctor who has speciality in treating diseases related to bones. The orthopedist will treat the disease with the help of surgery or by recommending correct medication.
