Learning Targets
- I can identify DNA and chromosomes as components that code for traits. #dok1
- I can recognize processes such as meiosis, replication errors, and mutations as sources of genetic variation. #dok1
- I can define statistics and probability in the context of trait variation in populations. #dok1
- I can ask questions to clarify the relationship between DNA, chromosomes, and inherited traits. #dok2
- I can explain how meiosis, replication errors, and mutations contribute to genetic variation. #dok2
- I can use probability concepts to describe variation in populations. #dok2
- I can make and defend a claim that inheritable genetic variations have multiple origins, including meiosis, replication errors, and environmental mutations, using supporting evidence. #dok3
- I can apply statistics to explain the variation and distribution of traits in a given population. #dok3
- I can construct explanations for how genetic instructions are passed from parents to offspring. #dok3
Big Ideas
- DNA and chromosomes carry genetic instructions that determine the traits passed from parents to offspring, and various processes can introduce variation in these instructions.
- Variation within populations, arising from genetic mechanisms and environmental influences, can be analyzed and described using concepts of statistics and probability.
Essential Questions
- How does DNA determine the traits that are inherited from parents to offspring?
- In what ways can genetic variation arise in a population?
- How do the processes of meiosis, replication errors, and environmental factors contribute to genetic diversity?
- How can statistics and probability help explain the variation and distribution of traits within a population?
- What evidence supports the mechanisms that lead to the inheritance and variation of traits?
