Welcome to the asynchronous genetics support documents provided by the Learning Resources Center at CU Denver. These documents can be used to review genetics concepts for a current genetics course or for professional admittance exams such as the DAT and MCAT.

The topics labeled with review provide foundation information for understanding the genetics concepts. Each genetics topic explored here has a brief overview of the concepts required to understand the content and an embedded worksheet. You will get the most out of these resources if you read and complete all material, complete any activities listed, and work in the order designated by the activity guide.

You can find a summary sheet of many important genetics concepts at the bottom of each topic page. If you need accommodations to utilize any of these resources, please contact us at LRC@ucdenver.edu.

Review: Defining Alleles →

This review sheet explains what it means to define alleles and why this is important.

Review: Genotype vs Phenotype →

This review sheet explains what genotype and phenotype are and explains how they are related.

Haplosufficiency and Mutations →

This set of documents covers the topic of haplosufficiency through reviewing dominance and mutations as well as terminology and examples of haplosufficiency.

Probability →

This set of documents explains the difference between the product and sum rules and their application to genetics. 

Pedigrees & Inheritance Patterns →

This set of documents covers why inheritance probabilities can differ based on modes of inheritance and applies this line of reasoning to pedigrees as a way to identify inheritance patterns. 

Double Recombinant →

This set of documents explains what recombination is, when it occurs, and what it means for genetic variability. Drawings and a hands-on modeling activity of single and double recombinants are used for this review. 

Dihybrid Cross vs Dihybrid Test Cross →

This set of documents reviews what these two crosses are, compares them, and provides examples of problems 

Dominant vs Recessive Epistasis →

This set of documents reviews what epistasis is and then compares dominant and recessive epistasis by expected ratio.

Complementation →

This set of documents explains complementation and provides an analogy for aid in memorization. Then, it compares terminology and provides practice of complementation problems.

Horizontal Gene Transfer →

This set of documents provides a comparison of three types of horizontal gene transfer. Practice with identifying the types of horizontal gene transfer and a note organization table are included.

Bacterial Plating: Testing Genotypes →

This set of documents explains how selective plating allows for genotyping bacteria. The foundational knowledge of how bacterial genotype indicates survivability on nutrient lacking and toxin containing plates can be practiced with these practice problems.

Interrupted Mating Experiments→

This set of documents explains conjugation experiments and provides practice for how to read an exconjugant graph.

Central Dogma of Biology (DNA Replication, Transcription, and Translation) →

The central dogma of biology explains the flow of genetic information to make a protein. This set of documents connects DNA replication, transcription, and translation as well as relates these processes to the gene expression.

Splicing vs Alternative Splicing →

This set of documents provides a comparison between splicing and alternative splicing.

Review: Parts of a Gene →

This document provides a brief explanation of the anatomy of a gene and explains the functions of each part.

Operons Overview →

This document explains what an operon is, what parts all operons must have, and what their functions are. This document can be used in combination with a review of lactose or tryptophan operons.

LAC Operon→

This set of documents provides an explanation for lactose operons, a table to organize notes about the function of part of the lac operon, and practice to test your knowledge.

Review: Cell Division →

This document provides a brief overview of mitosis and meiosis and a table to organize your notes on this topic.

Large Scale Chromosomal Rearrangements →

This set of documents provides an explanation of types of chromosomal rearrangement and then practice problems and an activity to help you learn to identify which type of rearrangement it is and how it occurred.

Summary Sheet of Genetics Topics

This sheet provides a map of how major genetics topics are all related to each other.

LRC graded assignment policy

The LRC supports our students learning and success. While our Tutors cannot give answers for any graded assignments, we can help by asking prompting questions, clarify concepts related to an assignment, and/or do similar practice problems. Please view the CU Denver Academic Integrity Policy for more information.

Please note, regardless of synchronous or asynchronous course delivery, students are unable to sign up for any LRC service that conflicts with a scheduled class time.

If you're unable to sign up for LRC services for any reason other than technical issues, please let us know by completing the form below. This will help us in future planning and how we deliver services to best meet the needs of our CU Denver student/community. Contact us at LRC@ucdenver.edu for questions.
