This study aimed at identifying the logical thinking level among 12 grade students and it's relation to their understanding level of genetic concepts. The study sample consisted of (362) male and female students in a group of Dakhilia Governorate's schools in the school year 2010-2011. To answer the study questions, two research instruments were constructed. They are Logical Thinking Test which consisted of (8) questions covered four skills that are: proportional reasoning, controlling variables, probalistic reasoning and correlational reasoning with a reliability value of (0.72). The second instrument is Genetic Concepts Test which consisted of (25) multiple choice questions with explanation in both classical genetics and modern genetics with a reliability value of (0.82). The study results revealed that: the logical thinking level among 12 grade students and their understanding level of genetic concepts were low. In addition, there was low significant relationship between logical thinking level among 12 grade students and their understanding level of genetic concepts at (α= 0.01). Also, there were statistically significant differences at (α= 0.01) in understanding level of genetic concepts between students, grades in gender variable in favor of female students, in the level of logical thinking variable in favor of abstract thinking students and in the interaction between them in favor of female abstract thinking students. The study recommends focusing on logical thinking and understanding of genetic concepts by using new teaching strategies and applying technology.
