This resource is intended for an introductory or intermediate-level college genetics course. It begins with an exploration of DNA and genome structure and continues with a study of the molecular mechanisms that drive gene expression. Concepts of classical transmission genetics are linked to the molecular mechanisms that underlie observable phenotypes. It concludes with specific topics that synthesize information from both molecular and transmission genetics, including consideration of topics like epigenetics, cancer biology, and evolution. Examples of both historical and current problems in genetics are presented, along with conversations of the relationship between genetics and society.

Precise modification of faulty genes for repair has been one of the most important goals in medicine. It is now finally within the realm of possibility thanks to the gene editing tool CRISPR. This microbial adaptive immune system can copy and cut specific DNA sequences. This animation provides a visual introduction of this revolutionary genetic tool.

The Plant Breeding E-Learning in Africa (PBEA) e-modules were originally developed as part of the Bill & Melinda Gates Foundation Contract No. 24576. Building on Iowa State University’s expertise with online plant breeding education, the PBEA e-modules were developed for use in curricula to train African students in the management of crop breeding programs for public, local, and international organizations. The authors of this textbook series adapted and built upon the PBEA modules to develop a series of textbooks covering individual topic areas. It is our hope that this project will facilitate wider dissemination and reuse of the PBEA modules’ content.
Crop Genetics provides an introduction to the genetic concepts of reproductive systems, recombination, mutation, segregation and linkage analysis, inbreeding, quantitative inheritance, fertility regulation, population genetics and polyploidy.

This textbook provides an introduction to plant genetics and biotechnology for the advancement of agriculture. A clear and structured introduction to the topic for learners new to the field of genetics, the book includes: an introduction to the life cycle of the cell, DNA and how it relates to genes and chromosomes, DNA analysis, recombinant DNA, biotechnology, and transmission genetics.

This laboratory manual for Genetics was created under an ALG Affordable Materials Grant. Topics covered include cell cycle mutations, cancer detection, cytogenetics, forensics, and mapping chromosomes.
