What This Document Is
This document is a lab packet for BIO 182 General Biology II at Arizona State University, focused on applying genetics and evolutionary principles to a simulated ecological problem. It presents a “mission memo” framing a scenario involving sunstalks and stalkleapers, where metal contamination and unintended genetic linkages threaten an ecosystem. The lab guides students through investigations related to heritability and potential gene editing solutions.
Why This Document Matters
This lab packet is essential for students enrolled in BIO 182 who need to practically apply concepts of heritability, natural selection, and genetic modification. It’s used during a lab session to analyze data and formulate solutions to a complex biological challenge. The exercise aims to reinforce understanding of how genetic traits influence adaptation and the potential consequences of genetic interventions.
Common Limitations or Challenges
This document provides the framework for a lab exercise, but it does not *teach* the underlying principles of genetics and evolution. Students are expected to have prior knowledge of these concepts. It also doesn’t provide pre-calculated results; students must perform the data analysis themselves. This preview does not include the datasets needed for analysis or the full results of the heritability estimations.
What This Document Provides
The full lab packet includes: a narrative framing the ecological problem, specific research questions regarding metal tolerance heritability and gene editing strategies, detailed instructions for estimating heritability through parental-offspring regression, and an appendix outlining the steps for analyzing the data. It also includes a partially obscured section of text (likely a distraction or puzzle element within the lab). This preview provides only a description of the document’s contents and purpose.
