The purpose of this article is to determine the components of conceptual ecologies that influence the understanding of concepts related to reproduction and inheritance in humans. After the lessons, multidimensional frameworks such as examination of concepts related to reproduction and inheritance, philosophical views on science and affective domains were applied to 119 tenth graders. Among them, nine students were selected on the basis of the results. And then a qualitative analysis on the components of conceptual ecologies has been made using interviews and questionnaires. The results show that the components of conceptual ecologies can be classified into several subcategories; philosophical views on science, epistemological commitments, affective domain, the nature of learning and problem solving strategies. And also, patterns of concept understanding were classified into categories of superficial concept, partial concept and elaborate concept according to attributes observed while surveying students. Students exhibiting the pattern of superficial concept could not understand cell division and hereditary concepts easily. They used subjective evaluation and social authority as epistemological commitments and their grade of affective domain was low. Those who had the pattern of partial concept understood some parts of the scientific concepts yet failed to form a connection between the concepts of reproduction and inheritance. The frequencies of the subcategory per component were similar. Students exhibiting the pattern of elaborate concept, however, were able to explain the concepts with a consistent logic meaningful structure. They used consistency in the epistemological commitments and had a high grade in the affective domain. Classifying the patterns of concept understanding according to the components of conceptual ecologies is important for organizing teaching strategies suitable for students of each pattern.
