Answer: The correct answer is-
C) Genes.
Traits are the particular characteristics of an individual ( such as eye color, skin color, hair color) that are depicted by genes ( segment of DNA that corresponds to particular protein, which determines specific trait of an individual).
Genes carry genetic information ( in the form of DNA sequence) that is passed from one generation to the next.
Gregor Mendel studied different genes ( corresponding to traits of pea plant) and their pattern of inheritance.
Thus, scientist used his data to conclude that traits are passed from parents to offspring through genes.
