Overview:

Cows have adapted to an incredible range of environments as they have provided people with milk, meat, leather, and draft power. As a response to the many uses and habitats of cattle, a wide variety of breeds have been developed. Breeders of beef and dairy cattle carefully select cows from known breeds that will yield the most meat and milk. In this video from Nature, learn about the most desirable traits in both beef and dairy cows.

14 ) Gather and synthesize information regarding the impact of technologies (e.g., hand pollination, selective breeding, genetic engineering, genetic modification, gene therapy) on the inheritance and/or appearance of desired traits in organisms.

Unpacked Content
Scientific And Engineering Practices:
Obtaining, Evaluating, and Communicating Information
Crosscutting Concepts: Cause and Effect
Disciplinary Core Idea: Heredity: Inheritance and Variation of Traits
Evidence Of Student Attainment:
Students:
  • Gather information about at least two technologies, which influence the inheritance of desired traits, with attention given to accuracy, credibility, and bias.
  • Synthesize information from multiple sources to provide examples of how technologies have changed the ways that humans are able to influence the inheritance of desired traits in organisms.
Teacher Vocabulary:
  • Technology (e.g., hand pollination, selective breeding, genetic engineering, genetic modification, gene therapy)
  • Inheritance
  • Traits
  • Synthesize
  • Bias
  • Credibility
  • Accuracy
  • Probability
Knowledge:
Students know:
  • Through technologies, humans have the capacity to influence certain characteristics of organisms.
  • One can choose desired parental traits determined by genes, which are then passed to offspring.
Skills:
Students are able to:
  • Gather information about multiple technologies that have changed the way humans influence the inheritance and/or appearance of desired traits in organisms.
  • Use multiple appropriate and reliable sources of information for investigating each technology.
  • Assess the credibility, accuracy, and possible bias of each publication and method used in the information they gather.
  • Use their knowledge of artificial selection and additional sources to describe how the information they gather is or is not supported by evidence.
  • Synthesize the information from multiple sources to provide examples of how technologies have changed the ways that humans are able to influence the inheritance of desired traits in organisms.
  • Use the information to identify and describe how a better understanding of cause-and-effect relationships in how traits occur in organisms has led to advances in technology that provide a higher probability of being able to influence the inheritance of desired traits in organisms.
Understanding:
Students understand that:
  • Cause-and-effect relationships in how traits occur in organisms has led to advances in technology that provide a higher probability of being able to influence the inheritance of desired traits in organisms.
