The study was aimed to investigate university students’ conceptions on three genetic concepts (Gene, DNA, chromosome). The study was carried out with 166 undergraduate students. To reveal students’ ideas about the three concepts, they were asked to complete a free word association test by using the term ‘gene’ as a stimulus word and to respond the following open questions: What is a gene, DNA, and chromosome in your opinion? Lastly, they were asked to draw the structure of gene, DNA and chromosome in a cell. Through network analysis and classification of their responses based on content similarities, the frequent concepts associated with gene were confirmed and their ideas about the three concepts were categorized. The students had alternative ideas about the three investigated concepts. In particular, more alternative concepts were observed for gene compared to DNA and chromosome. The drawing test revealed that their understandings was especially poor for the relationship between the three concepts. The results were compared with related literature and recommendations are provided.
