Scientists who study genetics are known as

Step 1: Analyze the question The question asks for the correct name for a scientist who studies genetics, which is the science of heredity and variation in living things.

Step 2: Explain the concept In science, the suffix -ist is added to a field of study to name the person who practices it:

• Biology → biologist
• Botany → botanist
• Zoology → zoologist
• Genetics → geneticist

Step 3: Check each option

• A. Genealogist: This is a person who studies family history and ancestry (family trees). It sounds similar to "genetics" but is not a science of heredity. ✘
• B. Geneticist: This is a scientist who studies genes, heredity, and variation. ✔
• C. Mendalists: This is not a standard scientific term. Gregor Mendel is called the "Father of Genetics", but people who study genetics are not called "Mendelists". ✘
• D. Genescientists: This is not an accepted term. ✘

Step 4: Answer The correct option is B. geneticist.

Exam tip: Do not confuse genealogist (family history) with geneticist (heredity and genes). Both start with "gene-", but only the geneticist studies genetics. For naming questions, match the field to its "-ist" form: genetics → geneticist.
