Essential Questions:
- What are the different inheritance patterns of genes?
- How can these different inheritance patterns be modeled through graphing and pedigrees?
- How does the random assortment and separation of chromosomes during meiosis result in unique offspring?
- How can errors in segregation lead to genetic disorders that can be visualized on a karyotype?
- How can probability be used to predict the inheritance of characteristics in offspring?
- Why are sexually produced offspring not identical to either of their parents?
Content Objectives:
Content Objectives:
- Explain from where an organism gets is unique characteristics.

- Explain how alleles segregate when more than one gene is involved.
- Identify Mendel's contribution to our understanding of genetics.
- Describe some of the exceptions to Mendel's principles.
- Explain the environment's role in the way genes determine traits.
- Identify how many sets of genes are found in most adult organisms.
- Describe the events that occur during each phase of meiosis.

Standards Addressed:
Standards Addressed:
- HS-LS3-1. Develop and use a model to show how DNA in the form of chromosomes is passed from parents to offspring through the processes of meiosis and fertilization in sexual reproduction.
- HS-LS3-2. Make and defend a claim based on evidence that genetic variations (alleles) may result from (a) new genetic combinations via the processes of crossing over and random segregation of chromosomes during meiosis, (b) mutations that occur during replication, and/or (c) mutations caused by environmental factors. Recognize that mutations that occur in gametes can be passed to offspring.
- HS-LS3-3. Apply concepts of probability to represent possible genotype and phenotype combinations in offspring caused by different types of Mendelian inheritance patterns.

** Review the study guide portion of the text (Sections 1.1, 1.2 and 1.3)
*** Complete the Key Terms and Questions section of the book to prepare for your test.
**** Define the key terms!
- How did the results of the F1 crosses influence Mendel's thinking?
- What did Mendel conclude determines biological inheritance?
- What is segregation?
- How is self-pollination similar to cross-pollination? How is it different?
- What evidence did Mendel use to explain how segregation occurs?
- What is probability?
- In your own words, define the terms genotype and phenotype.
- How did Mendel's experiments provide evidence for the principle of independent assortment?
- How does the principle of independent assortment help explain Mendel's results?
- Describe Gregor Mendel's contribution to our understanding of inherited traits.
- Use a seperate piece of paper draw a Punnett square to represent the cross of two pea plants, each heterozygous for tallness (Tt). Use the Punnett square to identify the probability of an offspring that is short.
- Why is incomplete dominance considered an explanation to Mendel's principles of inheritance?
- What is the relationship between the environment and phenotype?
- Petal color in roses is an example of incomplete dominance. Use a seperate piece of paper to draw a Punnett square to show the results of a cross between two pink roses (Rr). Use the model to predict the petal colors of the offspring.
- Describe the differences between meiosis I and meiosis II.
- Why are human games haploid instead of diploid?
- What events occur during meiosis I and meiosis II?
- How is meiosis similar to mitosis? How is it different?
- Why can chromosomes be described as units of linked genes?
- In asexual reproduction, mitosis occurs but meiosis does not occur. Which type of reproduction -sexual or asexual- results in offspring with greater genetic variation? Explain your answer.
