This lesson covers the basics of Genetics. Students will discuss genotypes and phenotypes, inheritance, dominant and recessive genes, and alleles. Students will study the inheritance traits of the fruit fly and will practice with Punnett squares. (Most appropriate for grade levels 8-12.)
Science Standards:
8.LS.2: Every organism alive today comes from a long line of ancestors who reproduced successfully every generation.
8.LS.3: The characteristics of an organism are a result of inherited traits received from parent(s).
High School Standards:
B.H.1: Cellular genetics
B.H.2: Structure and function of DNA in cells
B.H.3: Genetic mechanisms and inheritance
B.H.4: Mutations
B.H.5: Modern genetics
STEM Emerging Technology Connections:
The "Artificial Selection" lesson directly addresses Biotechnology by introducing students to this process as a means of modifying organisms for desired traits. The hands-on bean breeding activity provides a concrete example of artificial selection, highlighting its connection to the DoD's interest in biotechnology for various applications. The lesson effectively conveys the core principles and potential of this critical technology area.
