Complex Traits

Author(s): Nancy Moreno, PhD.

Mapping a Mutation

Activity 3: Slides 16–23.

Overview

Students learn about the genetic code, and how small substitutions within the code can lead to physical changes in individuals. Students use authentic data to uncover the single nucleotide polymorphism (SNP) responsible for long hair in dogs.


In the previous activity, students were introduced to the wide variety of characteristics found across breeds of dogs. They used information produced by modern genetics research to learn which breeds of dogs were most related and how genetics information is used commercially to help people figure the history and possible parentage of mixed breed dogs. These examples represent applications of genomics—a field that offers a new way of thinking about genes and heredity. 


Procedure

1. Introduce the topic of genes and genomes by presenting this slide.
