What This Document Is
This document is a problem set focused on the genetics of enhancers, specifically exploring how cell types are determined during development. It utilizes the well-studied model organism *Drosophila melanogaster* (fruit fly) and its eye development as a case study to illustrate key genetic principles. The material delves into the molecular mechanisms underlying cell fate specification, examining interactions between cells and the roles of specific genes in developmental processes.
Why This Document Matters
This resource is ideal for students enrolled in a General Genetics course, particularly those seeking to deepen their understanding of developmental genetics. It’s most beneficial when studying gene interactions, signaling pathways, and the genetic basis of cellular differentiation. Students preparing for exams or working through complex genetics problems will find this a valuable tool to reinforce their learning and explore real-world applications of genetic concepts. It’s designed to challenge your understanding and encourage critical thinking about how genetic mutations impact biological systems.
Topics Covered
* Cell fate determination during development
* Gene interactions and redundancy
* Receptor tyrosine kinase signaling pathways
