1. Definition of key terms
2. Brief Discussion of Genetics
2. Discussion of Mutations
3. Discussion of Selective Breeding in Animals
4. Connection of Principles of Genetics to the Modern Zoo
Objectives
Upon completion of this program, students should be able to:
1.) Define key terms in genetics: Genetics, Inheritance, DNA, & Genes
2.) Compare and Contrast mutations, deciding which may result in harmful, beneficial, or neutral effects to the structure and function of the organism
3.) Discuss the advantages of selective breeding in influencing the transfer of genetic information for captive animal populations.

o 7.L.4A.1 Obtain and communicate information about the relationship between genes and chromosomes to construct explanations of their relationship to inherited characteristics.
o 7.L.4A.2 Construct explanations for how genetic information is transferred from parent to offspring in organisms that reproduce sexually.
o 7.L.4A.5 Construct scientific arguments using evidence to support claims for how changes in genes (mutations) may have beneficial, harmful, or neutral effects on organisms.
o 7.L.4A.6 Construct scientific arguments using evidence to support claims concerning the advantages and disadvantages of the use of technology (such as selective breeding, genetic engineering, or biomedical research) in influencing the transfer of genetic information.
o 8.E.6B.1 Construct explanations for how biological adaptations and genetic variations of traits in a population enhance the probability of survival in a particular environment.
o H.B.4A.1 Develop and use models at different scales to explain the relationship between DNA, genes, and chromosomes in coding the instructions for characteristic traits transferred from parent to offspring.
NGSS:
o MS-LS3-1: Develop and use a model to describe why structural changes to genes (mutations) located on chromosomes may affect proteins and may result in harmful, beneficial, or neutral effects to the structure and function of the organism.
o HS-LS3-1: Ask questions to clarify relationships about the role of DNA and chromosomes in coding the instructions for characteristic traits passed from parents to offspring.
o HS-LS3-2: Make and defend a claim based on evidence that inheritable genetic variations may result from (1) new genetic combinations through meiosis, (2) viable errors occurring during replication, and/or (3) mutations caused by environmental factors.
