Abstract
The ability to learn and remember is variable within a population of a given species, including humans. This is due in part to genetic variation between individuals. However, only few genes have been identified that contribute to variation in learning and memory. Two inbred mouse strains, C57Bl/6J (B6) and DBA/2J (D2), show significant variation both in fear conditioning memory as well as primary responsiveness to fear. Several studies have identified quantitative trait loci (QTL) on chromosomes (Chr) 1 and 12 associated with performance in fear conditioning, but it is unclear if these QTL were associated with fear memory or innate fear responsiveness. To determine if these QTL are associate..
