Biology 2e is designed to cover the scope and sequence requirements of a typical two-semester biology course for science majors. The text provides comprehensive coverage of foundational research and core biology concepts through an evolutionary lens. Biology includes rich features that engage students in scientific inquiry, highlight careers in the biological sciences, and offer everyday applications. The book also includes various types of practice and homework questions that help students understand—and apply—key concepts. The 2nd edition has been revised to incorporate clearer, more current, and more dynamic explanations, while maintaining the same organization as the first edition. Art and illustrations have been substantially improved, and the textbook features additional assessments and related resources.

By the end of this section, you will be able to do the following:

Discuss Sutton’s Chromosomal Theory of Inheritance
Describe genetic linkage
Explain the process of homologous recombination, or crossing over
Describe chromosome creation
Calculate the distances between three genes on a chromosome using a three-point test cross

College-level course focusing on the principles of genetics. Course topics include structure and function of genes, chromosomes and genomes, biological variation, population genetics, use of genetic methods to analyze protein function, gene regulation, and inherited disease. Course features include lecture notes, assignments and solutions, and exams and solutions.
