The present study aims to look into what level of understanding high school students have about basic concepts of genetics and what difficulties they have in their learning genetics. The instruments used were an open-ended questionnaire and a semi-structured interview. As a result of examining students’ basic conceptions about genetics, we found that a large majority of the students had misconceptions in all the sections, namely, the concepts of gene, DNA and chromosome, the genetic characteristics of somatic and germ cells, the transfer of gene information, and the determination of sex. Speaking of students’ difficulties with genetics, some of their opinions in regard to textbooks were shortage of basic concepts explanation and the related exercise queries, shortage of mathematics-related explanation, and shortage of diverse activities of exploration, while some of their opinions in regard to teachers’ instruction method were no sufficient provision of diverse exercise queries and visual aids in class, more need of learning time in class, and more need of real life-related explanation in class.
