The I.3.2 developmental mutant has a single nucleotide deletion in the gene centromere identifier

The mutation I.3.2 was previously isolated from a genetic screen for genes on chromosome arm 2R that regulate cell growth in a genetic background that blocks apoptosis (Kagey et al. 2012). Here we describe the effort of undergraduate researchers in the phenotypic analysis and genetic mapping of I.3.2. These groups of undergraduates, working independently at two different institutions, participated in courses implementing the Fly-CURE pedagogy, which teaches genetics concepts through inquiry-based learning in a course-based undergraduate research experience (CURE) (Bieser et al. 2018; Mast et al. 2022).
