The ABC Model of Flower Development for Life Sciences

Understanding how a simple stem transitions into a complex, beautiful flower is one of the most fascinating topics in plant biology—and a frequent area of testing in life science examinations. This text-only course guides you through the foundational genetics of floral development. You will progress from basic plant anatomy terms to the sophisticated interactions of homeotic genes, enabling you to confidently solve complex genetic mutation problems and exam-style scenarios. What you'll learn: - Understand the core terminology of floral whorls and organ identity genes. - Master the classic ABC model and how classes of genes interact to form sepals, petals, stamens, and carpels. - Explore modern expansions of the model, including Class D and Class E genes along with MADS-box transcription factors. - Analyze homeotic mutant phenotypes and predict floral organ structures when specific genes are lost or modified. - Practice solving analytical genetics problems modeled after competitive life science exam questions. The course begins with essential terminology and the anatomy of a flower, then systematically introduces each gene class, and concludes with practical mutation analysis and written review exercises. Designed for undergraduate biology students and exam candidates in life sciences, this course requires no advanced biochemistry background.
