Chapter 12

Standards:

HS LS 3-1: Ask questions to clarify relationships about the role of DNA and chromosomes in coding the instructions for characteristic traits passed from parents to offspring.

HS LS 3-2: Make and defend a claim based on evidence that inheritable genetic variations may result from: 1 new genetic combinations through meiosis, 2 viable errors occurring during replication, and /or 3 mutations caused by environmental factors.

HS LS 3-3: Apply concepts of statistics and probability to explain the variation and distribution of expressed traits in a population.

Ch. 12 Objectives

12. 1 (HS-LS 3-3)

- Where does an organism gets its unique characteristics?
- How are different forms of a gene distributed to offspring?

12.2 (HS-LS 3-3)

- How can we use probability to predict traits?
- How do alleles segregate when more than one gene is involved?
- What did Mendel contribute to our understanding of genetics?

12.3 (HS-LS 3-3)

- What are some exceptions to Mendel's principles?
- How does the environment play a role in how genes determine traits?

12.4 (HS-LS 3-1 and HS-LS 3-2)

- How many sets of genes are found in most adult organisms?
- what events occur during each phase of meiosis?
- How is meiosis different from Mitosis?
- How can two alleles from different genes be inherited together?
