ABC Model of Flower Development: Life Sciences Exam Prep

Master the genetic rules that dictate how a plant forms its sepals, petals, stamens, and carpels. This text-based course breaks down the regulatory networks of the ABC model, translating a high-yield exam topic into clear, manageable concepts. You will transition from rote memorization to a deep, logical understanding of how homeotic genes interact to determine floral organ identity. What you'll learn: - Understand the fundamental anatomy of floral whorls and the core principles of homeosis. - Master the roles of Class A, B, and C genes and how their overlapping expression patterns define organ identity. - Analyze mutant phenotypes, including loss-of-function and gain-of-function mutations, using step-by-step logical deduction. - Explore modern extensions of the classic model, including the roles of Class D and E genes in the expanded ABCDE model. - Apply your knowledge to solve analytical exam-style scenarios and genetic interaction problems. The course begins with essential botanical terminology and foundational gene regulation concepts before guiding you through genetic combinations, evolutionary developmental biology (evo-devo) insights, and written practice problem walkthroughs. Designed for biology students and exam candidates, this course requires no advanced background in plant genetics to start. Begin reading today to build a solid foundation in plant developmental genetics and boost your exam readiness.
