The correct answer is D. Factors for some traits are inherited from parents
Explanation:
Gregor Mendel was a scientist that lived during the 19th century, mainly recognized as the founder of genetics. During his life Mendel conducted multiple experiments using pea plants to determine the way traits are inherited, this led to the laws of Mendelian inheritance which are a set of principles or laws that describes the way certain traits are inherited over others and in some cases hereditary traits are mixed, which apply to other organism and not only to plants. In these laws, Mendel included the study of the plant height, color, and shape through multiple generations of plants which allowed Mendel to prove his principles about the way traits are inherited in different generations. Thus, the main contribution to the science of Gregor Mendel was the creation of laws that described the way traits are inherited from parents or between generations of different organisms.
