Answer:
The correct answer is geneticist.
Step-by-step explanation:
A geneticist is a biologist who studies science which deals with the genes studying about inheritance, activation, inactivation and mutation.
The genes are inherited from the parents to the offspring through sexual reproduction in which half of the genes are transmitted by mother and rest half by father.
The study of inheritance pattern is helpful in studying the diseases passed on and helpful in making a pedigree chart of that character.
Thus, a geneticist is the correct answer.
