Overview:
Genome Science is concerned with the function and diversity of genomes within and across species as well as with applications, policies and ethics surrounding genetic and genomic data. This resource aims to introduce key concepts and current technologies and techniques in genome science to undergraduates majoring in biology or sub-disciplines of biology. This is accomplished by engaging student groups in an activity that explores how genomic variation can benefit food security. This three-stage Problem Based Learning (PBL) exercise,dubbed “Food Security: Understanding the Role of Genomic Variation and Plant Breeding,” guides students from understanding what food security entails, particularly environmental stress on crop production, to discovering how high-throughput sequencing (HTS) data on genomic variation can aid in solving such problems.The PBL resource is intended to be given over three separate class periods. Each stage includes a reading with new terms defined in the margins and a set of guiding questions. Students work in groups of three or four to complete each stage of the problem. Each stage takes about an hour including time for class-wide discussion of select questions. Students are ultimately challenged to think about how HTS data on genomic variation can help solve issues with food crop production. Following this exercise, students should be able to discuss approaches used to preserve and characterize genetic diversity and how this impacts plant breeding and food security.
