This study aimed to obtain the scientific concept in genetics when experimental modules of Mendelian genetics using RcBr would be applied to the preservice teachers. This experimental modules using RcBr put an emphasis on Mendel's dihybrid cross experiments for the scientific concept in genetics being placed. Results are as follows: Experimental modules of Mendelian genetics using RcBr was found to be very effective in enhancing the concept achievement in genetics by the preservice teachers. Their concept achievement in genetics right after the application of developed modules seemed to be sustained even after four-month period. Results from the word association test indicated that preservice teachers' ability of formulating diverse and stronger connections between the concepts in genetics could be witnessed while revealing its normalizing aspect within the cognitive structure. Qualitative analysis based on interviews showed that Mendelian genetics experiments using RcBr was determined to be effective for the preservice teachers who had some difficulties in understanding concepts in genetics. Preservice teachers have shown some positive responses on this type of learning and contents utilizing experimental modules of Mendelian genetics using RcBr and accepted that these modules helped them in obtaining concepts in genetics. They also mentioned that the process of growing RcBr and conducting a similar experiments that Mendel himself conducted a long time ago to be quite fascinating. This suggested that the developed modules could be used as a very useful learning material for the instructors who teach genetics to the preservice teachers.
