Genetics, Heredity, and Human Intervention

Guiding Question: How can humans influence the inheritance of desired traits in organisms over time?


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. 

Students should be able to:

 

  1. Make a model that includes genes (or chromosomes), proteins (or amino acids), and traits of organisms.
  2. Describe the relationship between these parts, such as that every gene has a certain structure, which determines the structure of a specific set of proteins.
  3. Explain the connection between structural changes to genes (mutations) and possible effects to the organism.

LS4-5. Gather and synthesize information about the technologies that have changed the way humans influence the inheritance of desired traits in organisms.

Students should be able to…

 

  1. Obtain information about at least two technologies that have changed the way humans influence the inheritance of desired traits in plants and animals.
    • Examples could include gene therapy, genetic modification, and selective breeding of plants and animals.
  2. Evaluate the information by assessing its credibility, accuracy, and bias, to provide examples of how technologies have changed the ways that humans are able to influence the inheritance of desired traits, or to describe how the technology leads to changes in inherited traits over time.
