Modern Understandings of Inheritance Resources
Overview
This chapter begins with the details of the Chromosome Theory of Inheritance and moves onto discuss homologous recombination and the creation of new chromosomes. It also describes genetic linkage maps and how to calculate distances of genes on chromosomes. The second part of this chapter is focused on karyotypes, nondisjunction and creation of individuals with abnormal numbers of chromosomes.

Chapter 13: Modern Understandings of Inheritance
OpenStax: Biology 2e
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.
