Conservation genetics and population connectivity bring molecular biology and wildlife conservation together in this Grade 12 Science worksheet for Biology 30. Students explore how genetic diversity, inbreeding, effective population size, and gene flow influence wildlife population viability, then apply these concepts to habitat fragmentation and conservation planning in Alberta.

The central focus is the connection between genetic evidence and real conservation decisions. Students examine how scientists use molecular markers and heterozygosity to assess genetic variation, why isolated populations may face increased genetic risks, and how habitat corridors can support genetic exchange. Examples involving Alberta boreal caribou and isolated prairie populations help connect genetic concepts to regional environmental challenges.

From genetic evidence to wildlife recovery

The reading passage introduces the scientific vocabulary and relationships needed to evaluate population health. Students consider why a large total population does not necessarily have a large effective population size, how inbreeding can increase the expression of harmful recessive alleles, and why habitat fragmentation may restrict movement between groups.

Rather than treating genetic diversity as the only measure of survival, the resource highlights the importance of combining genetic information with demographic and habitat evidence. Students also examine how conservation teams can use these findings to prioritize habitat protection, improve connectivity, plan recovery strategies, and monitor outcomes over time.

Activities and scientific reasoning

• Multiple-choice questions examine conservation genetics, heterozygosity, inbreeding, effective population size, gene flow, and habitat corridor planning.
• True-or-false statements address misconceptions about population size, genetic diversity, habitat fragmentation, and the limitations of individual measures.
• Short-answer responses ask students to explain genetic risks in isolated populations, distinguish effective population size from total population size, and apply genetic evidence to boreal caribou conservation.
• A labelled diagram activity supports work with visual information related to the lesson.
• A categorization activity gives students another way to organize relevant concepts.
• A short-note section provides an opportunity to record and consolidate key information.

What the download includes

• Student worksheet: A reading passage, knowledge-check questions, written explanations, and diagram and categorization activities.
• Student Notes lines: Writing space at the bottom of the worksheet for recording important ideas.
• Separate answer key PDF: A distinct file for checking student responses.

Classroom use and review

Use this conservation biology worksheet during Biology 30 instruction, as follow-up to a lesson on population genetics, for independent practice, or for assessment preparation. The passage establishes the context, while the questions require students to explain relationships between genetic processes and population viability rather than simply recall terminology. The Alberta wildlife examples also provide a concrete starting point for discussing how scientific evidence informs habitat corridor planning and species recovery.

With a separate answer key and practical teacher guidance, this Grade 12 resource supports both student practice and lesson preparation. Alberta is the specified curriculum framework, making the worksheet relevant to teachers seeking population genetics and wildlife conservation content for their Science program.
